Misc Notes for psprint directory. This is the print processor directory. The module that is built called psprint.dll, is used as the installed print processor to the Win32 spooler. The test program (test.c) emulates the macprint spooler code, by submitting a job via the same (or similar) interface as the macprint spooler component. To use the test program you should have a printer configured as "PSTODIB Local Test Printer" this way you can type "test " and have the job submitted correctly The print processor code uses a NT function call to set the access token of the primary thread of the process created to actually image the postscript job, see the explanation of this in psprint.c where CreateProcess is called.
