How to Troubleshoot the Spooler SubSystem App Error
When you try to add a printer to a Windows XP computer, you may receive the following error message: “Spooler Subsystem App has encountered a problem and needs to close.” When installing the new printer, the error message may be displayed, and the printer will uninstall. The new printer will then be removed from the Printers folder in the Control Panel. This problem is caused by older DLL files on the computer, and it has a simple and straightforward solution.

Tips & Warnings
Other related similar error messages you may get include: "Operation could not be completed. The print spooler service is not running." and "Spooler SubSystem App stopped working and was closed." This problem is particularly common when trying to install certain HP Laserjet printers and also on computers that were upgraded from an earlier version of Windows, particularly Windows 98. The printer may have worked perfectly using the earlier version of Windows, but you may have difficulties installing the printer under Windows XP.
