>Recently, I've had the need to send files directly to a printer port. I have had success copying files to network printer ports, but not to physical printer ports (i.e. LPT1). As long as LPT1 is a captured port, the copy file myfile.pcl to LPT1 command works, but I get mixed results when LPT1 is actually a local printer. One system I get File access is denied. On my work system, I get Invalid Seek Offset and at home I get the blue screen of death!

You've not provided us with the return from GetLastError(), so this is a SWAG at best, but the most common errors people make are:

- failing to pass a 0 as the third parameter, to tell it not to fail if the target exists
- misspecifying the port name; the default printer port is LPT1:, not LPT or LPT1
- naming an unassigned device; under NT/2K, there is no default device assigned to PRN:
