Managing Roaming Printers with Roaming Profiles in Windows Client Environments

Table of Contents

Roaming profiles in Windows client environments are designed to provide users with a consistent desktop experience across different machines. A key component of this experience is the user’s personalized settings, which are stored in the roaming profile. By default, this includes settings related to installed printers, particularly the user’s designated default printer. The system stores this preference under the HKEY_CURRENT_USER registry hive, which is part of the user’s roaming profile data (NTUser.dat). Consequently, when a user logs onto a different computer, their default printer setting follows them, aiming to maintain continuity.

While this default behavior is intended to be convenient, it can present challenges in certain organizational setups. Environments like computer labs, shared workstations, or branch offices often require users to default to a printer local to the specific machine or location they are using, regardless of their usual default printer stored in their profile. Allowing the default printer to roam can lead to user frustration, increased support calls, and wasted resources if print jobs are inadvertently sent to printers in different physical locations. Therefore, administrators often need to alter this default roaming behavior to ensure printers are assigned logically based on the user’s current login location. This article outlines methods to achieve this customization, enabling administrators to enforce location-specific or machine-specific default printers for users with roaming profiles.

Important Considerations and Warnings

Before implementing any changes related to managing printers or modifying the Windows registry, it is crucial for corporate administrators to understand the potential impact of these actions. The methods described below involve direct manipulation of the system registry or execution of scripts with elevated permissions. Incorrectly modifying the registry can lead to severe system instability, data loss, or render the operating system inoperable. It is essential to proceed with extreme caution and follow best practices for system administration.

It is strongly recommended that you thoroughly test any method described in this article within a controlled test environment before deploying it to production systems. This allows you to verify functionality, identify potential conflicts, and ensure the changes do not negatively impact other system settings or user experiences. Familiarity with Registry Editor (Regedit.exe) and scripting languages like VBScript is assumed. While Microsoft provides these examples for illustration, they are provided without warranty, and Microsoft support may assist in explaining functionality but will not modify or build custom solutions based on these examples.

The following sections detail two methods to prevent the default printer from roaming with the user profile and instead set a specific default printer based on system configuration or location.

Methods to Alter Roaming Printer Behavior¶

Since the default printer setting is stored within the user’s HKEY_CURRENT_USER hive, which roams with the profile, the approach to prevent this involves overriding or resetting this setting after the user profile (including its roaming printer setting) has loaded. This typically happens during the user login process. The methods presented here leverage system mechanisms that execute during startup or login to set a desired default printer, effectively overriding the one that roamed with the profile.

Method 1: Automating Default Printer Setting via Registry Import¶

This method involves exporting the desired printer configuration from the registry, cleaning up the export file to include only the default printer setting, and then configuring the system to import this setting silently using Regedit.exe every time a user logs in. This approach is suitable for scenarios where specific machines or groups of machines should always default to a particular printer.

Here’s a breakdown of the steps:

1. Export the Desired Printer Setting:

   • Log in to a computer where the desired default printer is already installed and set as the default for a test user.
   • Open Registry Editor (Regedit.exe).
   • Navigate to the following registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows
   • With the Windows key selected, go to File > Export. Save the .reg file to a temporary location. Name it something descriptive, like DefaultPrinterExport.reg. This file now contains all settings under that specific Windows key for the current user, including the default printer information.

2. Modify the Exported Registry File:

   • Open the exported .reg file (DefaultPrinterExport.reg) in a text editor (like Notepad).
   • The file will start with something like Windows Registry Editor Version 5.00 followed by a blank line.
   • It will then have the registry path in brackets: [HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows].
   • Below the path, you will see several value names and their data. The default printer is stored in the value named "Device".
   • Crucially, delete all lines under the registry path line except the line that starts with "Device"= and its associated data.
   • Ensure the file contains the Windows Registry Editor Version line, a blank line, the registry path line, the "Device"= line, and at the very end, another blank line. The final blank line is essential for the .reg file format to be parsed correctly.
   • Save the modified file. This clean .reg file now contains only the information needed to set the default printer for the user whose profile is being loaded.

3. Configure the System to Import the Setting:

   • The goal is to run the silent registry import command whenever a user logs on to the specific machine. A common method is to add a command to the Run key in the machine’s registry. This key specifies programs that should run automatically for any user logging into that computer.
   • Open Registry Editor (Regedit.exe) again, this time navigating to a machine-specific key.
   • Navigate to the following registry key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
   • Right-click in the right-hand pane and select New > String Value.
   • Name the new value something like ResetDefaultPrinter.

4. Set the Command to Execute:

   • Double-click the ResetDefaultPrinter string value you just created to edit its data.
   • In the “Value data” field, enter the command to silently import your modified .reg file using Regedit.exe. The command format is: REGEDIT.EXE -S "path\to\your\ModifiedPrinter.reg"
   • Replace "path\to\your\ModifiedPrinter.reg" with the actual path where you have saved the modified .reg file. This path should be accessible by the computer during the login process, such as a path on a network share or a reliable local path (though a network share is preferable for easier management across multiple machines).
   • For example, if the modified file LAB1_Printer.reg is stored in a shared folder Printers on \\YourServer, the value data would be: REGEDIT.EXE -S "\\YourServer\Printers\LAB1_Printer.reg"
   • Click OK to save the value.

Now, whenever a user logs into a machine with this registry setting configured, the specified .reg file will be silently imported into their HKEY_CURRENT_USER hive after their profile loads. This action will set the "Device" value to the desired printer, overriding the default printer that roamed with their profile. This method is straightforward but requires creating and managing separate .reg files and Run key entries for each group of machines needing a different default printer.

Method 2: Using a VBScript for Dynamic Printer Assignment Based on Computer Name¶

This method offers more flexibility by using a simple VBScript that executes during login. The script can read the computer’s name and, based on predefined patterns or lists, set the appropriate network printer as the default. This is highly effective in environments where computer names follow a naming convention that indicates their physical location or functional group (e.g., LAB1-PC01, OFFICE2-WS15).

Here’s how to implement this method:

1. Create the VBScript File:

   • Open a text editor and copy the following VBScript code.
   • Save the file with a .vbs extension, for example, DefaultPrinterScript.vbs. Store this file in a location accessible by the computers during login, such as a network share.

   Option Explicit
   DIM RegEntry, ComputerName
   
   ' Path to the ComputerName value in the registry
   ' This path reads the actual computer name used by the system
   RegEntry = "HKLM\SYSTEM\CurrentControlSet\Control\ComputerName\ComputerName\ComputerName"
   
   ' Read the computer name from the registry
   ComputerName = ReadRegValue(RegEntry)
   
   ' --- Modify the IF lines below to match your computer naming conventions and printers ---
   ' Example: If the computer name contains "LAB1-", set \\LAB1\LaserJet as default
   if InStr(1, ucase(ComputerName), "LAB1-", vbTextCompare) > 0 then
       call SetPrinter("\\LAB1\LaserJet")
       wscript.quit ' Exit after finding a match and setting the printer
   end if
   
   ' Example: If the computer name contains "LAB2-", set \\LAB2\Printer2 as default
   if InStr(1, ucase(ComputerName), "LAB2-", vbTextCompare) > 0 then
       call SetPrinter("\\LAB2\Printer2")
       wscript.quit ' Exit after finding a match and setting the printer
   end if
   
   ' Example: If the computer name contains "OFFICE-", set \\OFFICE\Printer3 as default
   if InStr(1, ucase(ComputerName), "OFFICE-", vbTextCompare) > 0 then
       call SetPrinter("\\OFFICE\Printer3")
       wscript.quit ' Exit after finding a match and setting the printer
   end if
   
   ' Add more IF statements as needed for other locations/naming patterns
   ' Example: If no specific pattern matches, perhaps set a general default printer
   ' call SetPrinter("\\GeneralServer\GeneralPrinter")
   ' Note: If you add a general default, remove wscript.quit from previous IF blocks
   ' if you want it to be a fallback. With wscript.quit, only the *first* match runs.
   
   ' wscript.quit ' Ensure script exits after execution or if no patterns match
   
   ' *** This subroutine installs and sets the default printer ***
   ' Takes the full network path of the printer (e.g., \\PrintServer\PrinterShareName)
   Sub SetPrinter(ByVal PrinterPath)
       DIM WshNetwork
       On Error Resume Next ' Handle potential errors, e.g., printer already exists, access denied
       Set WshNetwork = CreateObject("WScript.Network")
   
       ' Attempt to add the printer connection
       ' This is necessary if the user hasn't connected to this printer before
       WshNetwork.AddWindowsPrinterConnection(PrinterPath)
       ' Check if adding the printer failed (optional, more advanced error handling could be added)
       ' If Err.Number <> 0 Then WScript.Echo "Error adding printer " & PrinterPath & ": " & Err.Description
       Err.Clear ' Clear any potential errors
   
       ' Attempt to set the printer as default
       WshNetwork.SetDefaultPrinter PrinterPath
       ' Check if setting default printer failed (optional)
       ' If Err.Number <> 0 Then WScript.Echo "Error setting default printer " & PrinterPath & ": " & Err.Description
       Err.Clear ' Clear any potential errors
   
       Set WshNetwork = Nothing
   End Sub
   
   ' **** This function returns the data in the registry value ****
   ' Used here to read the computer name
   Function ReadRegValue(ByVal RegValue)
       DIM WSHShell
       Set WSHShell = WScript.CreateObject("WScript.Shell")
       ReadRegValue = "" ' Initialize return value
       On Error Resume Next ' Handle case where registry value might not be readable (unlikely for computer name)
       ReadRegValue = WSHShell.RegRead(RegValue)
       On Error GoTo 0 ' Turn off error handling
       Set WSHShell = Nothing
   End Function
   

2. Modify the Script’s Logic:

   • The key part of the script is the block of IF statements. You need to modify these lines to match your specific computer naming conventions and the corresponding network printer share names.
   • For each required mapping, create an If...then...end if block.
   • Modify the string inside the InStr function (e.g., "LAB1-") to be a unique part of the computer names in that location.
   • Modify the string inside the SetPrinter call (e.g., "\\LAB1\LaserJet") to be the network path (\\PrintServerName\ShareName) of the printer that computers with that naming pattern should use.
   • The ucase(ComputerName) part makes the comparison case-insensitive. The InStr(1, ..., ..., vbTextCompare) > 0 part checks if the specified pattern exists anywhere within the computer name.
   • The wscript.quit after each successful SetPrinter call ensures that as soon as a match is found and the printer is set, the script stops. This is useful if a computer name might match multiple patterns (e.g., “LAB1-PC-05” might match “LAB1-” and “PC-“). If you want the script to continue checking or have a fallback, remove wscript.quit from the specific IF blocks.

3. Configure the System to Run the Script:

   • Similar to Method 1, you can use the Run key to execute this script for every user logging into the machine.
   • Open Registry Editor (Regedit.exe) and navigate to: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
   • Right-click in the right-hand pane and select New > String Value.
   • Name the new value something like SetLocationPrinter.

4. Set the Command to Execute:

   • Double-click the SetLocationPrinter string value.
   • In the “Value data” field, enter the command to run the VBScript using wscript.exe. The format is: WSCRIPT.EXE "path\to\your\DefaultPrinterScript.vbs"
   • Replace "path\to\your\DefaultPrinterScript.vbs" with the actual path to your saved .vbs file. This path must be accessible by the computer during user login (e.g., a network share).
   • For example, if the script DefaultPrinter.vbs is stored on a share Scripts on \\YourServer, the value data would be: WSCRIPT.EXE "\\YourServer\Scripts\DefaultPrinter.vbs"
   • Click OK to save the value.

Now, whenever a user logs into a computer with this setting, the VBScript will run. It will check the computer’s name against the patterns defined in the script and set the corresponding printer as the user’s default. The SetPrinter subroutine handles adding the network printer connection if it doesn’t already exist for the user and then sets it as the default.

Note: Instead of using the Run key, you can also configure this VBScript to run as a user login script via Group Policy. This is often a more centralized and manageable approach in larger Active Directory environments. Both methods achieve the goal of executing code during user logon to override the roaming default printer. Ensure the Windows Scripting Host is installed and enabled on client machines if using this method.

Comparing the Methods¶

Both methods effectively address the issue of roaming default printers by enforcing a machine-specific or location-based printer preference upon user login. However, they differ in complexity, flexibility, and management overhead:

• Method 1 (Registry Import):

  • Pros: Relatively simple setup for a fixed mapping (one specific printer for one specific machine configuration). No scripting knowledge required beyond basic text file editing. Silent import is clean.
  • Cons: Requires creating and managing separate .reg files for each distinct default printer needed. Less flexible if the logic needs to be more complex than a simple one-to-one mapping (e.g., different printers based on user group on a specific machine type). Deployment of .reg files and Run key settings across many machines can be cumbersome without central management tools like Group Policy.

• Method 2 (VBScript):

  • Pros: More flexible and dynamic. Can incorporate simple logic (like checking part of the computer name) to map many machines to different printers using a single script file. Easier to update printer mappings by modifying one central script file. Can potentially be expanded to include more complex logic if needed.
  • Cons: Requires basic VBScript knowledge to modify and troubleshoot. Dependent on consistent computer naming conventions. Potential for script errors if not carefully written and tested. Requires ensuring Windows Scripting Host is functional.

The choice between methods depends on the complexity of your printer mapping requirements and your administrative comfort level with registry editing versus scripting. For simple scenarios, Method 1 might suffice. For environments with structured naming conventions and varying printer needs, Method 2 offers better scalability and centralized management of the logic.

Alternative Approaches: Group Policy Preferences¶

While the provided methods are effective, a more modern and often preferred approach in Active Directory environments is using Group Policy Preferences (GPP). GPP offers granular control over deploying settings, including printers, and can target users or computers based on a wide range of criteria without needing custom scripts or manual registry edits.

With GPP, you can create a “Printers” preference item linked to a Computer Configuration or User Configuration Group Policy Object (GPO). Within the preference item, you can define shared printers to deploy and use “Item-level targeting” to specify exactly which computers or users should receive which printer. Targeting criteria can include:

• Organizational Unit (OU): Apply printers to computers or users within a specific OU (e.g., Lab Computers OU).
• Security Group: Apply printers based on computer or user group membership.
• Computer Name: Target specific computers or computers matching a wildcard pattern (similar to Method 2’s script logic, but graphical).
• IP Address Range: Target computers based on their network subnet (useful for location-based printers).
• Operating System: Apply settings based on the Windows version.

By using GPP, you can:

• Deploy shared printers (TCP/IP printers are also an option but often require more complex targeting).
• Set a deployed printer as the default printer.
• Replace existing default printers.
• Install printer drivers automatically (if configured correctly on the print server and GPO).

GPP consolidates printer management within the standard Group Policy infrastructure, reducing the need for custom scripts or manual registry modifications, especially at scale. For many administrators managing roaming profiles in a domain environment, GPP offers a more robust and manageable solution compared to the methods outlined above, which are more akin to traditional login script or manual configuration techniques. While not part of the original article, understanding GPP is crucial for comprehensive printer management in modern Windows client environments.

Best Practices for Managing Printers with Roaming Profiles¶

Regardless of the method chosen, several best practices should be followed to ensure a smooth and reliable printer management experience for users with roaming profiles:

• Standardize Printer Naming: Use clear and consistent naming conventions for your network printer shares (e.g., [Location]-[PrinterModel] or [Building]-[Floor]-[Room]).
• Use Print Servers: Centralize printer sharing and management on dedicated print servers. This simplifies deployment, driver management, and troubleshooting compared to sharing printers directly from workstations.
• Driver Management: Ensure that necessary printer drivers are available to client machines. Consider using Point and Print restrictions via Group Policy to specify trusted print servers and manage driver installation without requiring administrative privileges for users.
• Thorough Testing: Always test printer deployment methods in a pilot group or test environment that accurately reflects your production setup before wide deployment. Test with different user accounts and on various machine types.
• Documentation: Document your printer deployment strategy, including naming conventions, scripts used, registry keys modified, and Group Policy settings configured. This is invaluable for troubleshooting and onboarding new administrators.
• Consider User Experience: While enforcing location-based printers is important, consider if there are scenarios where users do need access to printers in other locations. Ensure the enforced default doesn’t prevent users from manually adding or selecting other available printers if needed.

Troubleshooting Common Issues¶

When implementing custom printer settings during user login, you might encounter issues. Here are some common problems and troubleshooting steps:

• Printer Not Set as Default:

  • Check the path in the Run key (or login script). Is it correct? Is the path accessible from the client machine?
  • Verify that the .reg file (Method 1) or .vbs script (Method 2) is present and correctly named at the specified path.
  • Check permissions. Does the user account have permissions to read the file/script from the network share?
  • For Method 1: Open the .reg file in a text editor and double-check the format, especially the blank lines and the exact key path. Try manually double-clicking the .reg file on a test machine (outside of the login process) to see if it imports successfully without errors.
  • For Method 2: Run the VBScript manually from a command prompt using cscript.exe DefaultPrinterScript.vbs. cscript provides command-line output which can help show script errors. Check the script logic carefully for typos or incorrect printer paths/computer name patterns. Ensure the print server name and share name are correct and accessible. Does the user have permissions to add a printer from that print server?

• Error Messages During Login:

  • If using the Run key, errors might appear in the Windows Event Log (Application or System logs).
  • For scripts (Method 2), wscript.exe might show a dialog box with script errors. Running with cscript.exe can help capture these errors more easily.
  • Permission denied errors often indicate the user account lacks the necessary rights to read the script/file or to perform the requested action (like adding a printer connection).

• Printer Appears But Not Default:

  • Confirm that the command/script specifically sets the printer as default (e.g., using SetDefaultPrinter in VBScript or the correct "Device" value in the .reg file).
  • Ensure no other process or script is running after yours that might be changing the default printer setting. Login scripts or Group Policy Objects might run in a specific order.

• Script Not Running:

  • Check the Run key entry for typos.
  • Verify the path is correct and accessible.
  • Ensure wscript.exe (Method 2) is present and registered on the system.
  • Check if security software (antivirus/endpoint protection) is blocking script execution.

By carefully reviewing the configuration steps, checking logs, and testing components individually, administrators can effectively troubleshoot issues related to custom printer assignments for roaming profile users.
