More information

This problem occurs because the GDI library is not thread-safe and cannot handle calls from different threads for the same print job. The Snaprint service uses I/O completion port thread pooling to minimize thread usage and to be able to print to 500 printers at the same time. When I/O completion ports are used, thread switching occurs and GDI fails. To correct this problem, the hotfix modifies the Snaprint service to now call the GdiSetBatchLimit function with the dwLimit parameter set to 1 at the start of each thread in the print server to prevent data from being cached.
