Citrix AddPrinter Utility

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.
