The following will copy a file to the default PRN device:

FUNCTION CopyFileToDevicePRN
LPARAMETER cFileToPrint
DECLARE SHORT CopyFile IN Win32API ;
   STRING cFileToCopy, ;
   STRING cTargetFile, ;
   SHORT nFailIfExists

RETURN CopyFile(cFileToPrint,'PRN',0) = 1

* If no device PRN has been defined to the OS, it ain't goinna work
IF CopyFileToDevicePRN('MyPrintFile')
   * The file will be copied to the target device and VFP will not wait on completion
ELSE
   * The copy operation failed to be started
ENDIF

The CopyFileToDevicePRN() function should really be made more robust, since if API call CopyFile() returns a 0, you really need to invoke the API call GetLastError() to get the real return status. But it's a starting place...
