first you have to do that:

set prin to myprint.txt

after that if you want to use ? command use it. don't use ??? command...

if you want to prin a report file. create your report in foxpro Dos and use report to ascii command in VFP. don't open report in VFP anymore!..

after that. you ready to print your report :)

  set prin to
    
DECLARE INTEGER CopyFile IN kernel32;
	STRING lpSrcFile, STRING lpDstFile, INTEGER bFail
CopyFile("myprint.txt","prn", 0)

that api support even network printers (you have to use network printers name like : secretary\\ibm ) ...
