Many driver problems in the Terminal Services environment revolve around poor multi-threaded performance, which in turn can cause Print Spooler instability. Problematic multi-threaded performance is usually exposed when multiple users connect to a Terminal Server simultaneously using the same print driver. Symptoms include the failure to autocreate client printers, increased thread count of the Printer Spooler and/or Citrix Print Manager services, and possibly the unresponsiveness and/or unexpected termination of these services (crashes).
This tool can be used to simulate multiple sessions autocreating printers using the same print driver.
It can also be used to compare the following among various drivers:
• CPU load incurred while creating a printer using a particular driver
• Time required to successfully create a printer using a particular driver
