The Terminal Server Printer Driver Redirection Wizard will help you troubleshoot and replace print drivers that were unsuccessfully redirected.

TSPrint Terminal Server Printing TSPrint is the RDP printing software for Terminal Services, Remote Desktop, VDI, or Citrix environments. Simple implementation and ease-of-use, coupled with an affordable licensing system, makes TSPrint one of the most popular remote desktop printing solutions on the market. Increase the stability of servers, without installing printer drivers on any terminal server. Clients print directly to their local printers from the terminal server, without additional administrator time required for implementation or configuration.

Printer Driver Isolation • • 4 minutes to read • Contributors • In this article Printer driver isolation improves the reliability of the Windows print service, by enabling printer drivers to run in processes that are separate from the process in which the print spooler runs. Support for printer driver isolation is implemented in Windows 7, Windows Server 2008 R2 and later operating systems. For Windows 7 and Windows Server 2008 R2, an inbox printer driver must support printer driver isolation and be able to run in an isolated process. Previous Versions of Windows In previous versions of Windows, including Windows Server 2008, printer drivers always ran in the same process as the spooler. Printer driver components that ran in the spooler process included the following: • Print driver configuration modules • Print processors • Rendering modules The failure of a single print driver component could cause the print subsystem to fail, halting print operations for all users and for all print components.

New Versions of Windows With Windows 7 and Windows Server 2008 R2, an administrator can, as an option, configure a printer driver to run in an isolated process--a process that is separate from the spooler process. By isolating the driver, the administrator can prevent a fault in a driver component from halting the print service. For more information about the spooler functions, see.

Driver Isolation Support in INF Files By default, if the INF file that installs a printer driver does not indicate that the driver supports driver isolation, the printer class installer configures the driver to run in the spooler process. However, if the INF file indicates that the driver supports driver isolation, the installer configures the driver to run in an isolated process.

An administrator can override these configuration settings and specify, for each driver, whether to run the driver in the spooler process or in an isolated process. To support driver isolation, the INF file that installs a printer driver can use the DriverIsolation keyword to indicate whether the driver supports printer driver isolation. Setting DriverIsolation=2 indicates that the driver supports driver isolation. Setting DriverIsolation=0 indicates that the driver does not support driver isolation. Omitting the DriverIsolation keyword from the INF file has the same effect as setting DriverIsolation=0. Spooler Functions for Driver Isolation Settings The following table shows the spooler functions that an administrator can use to configure the driver-isolation settings. Function name Operation Get the driver-isolation settings for a printer.
