How to send .prn file directly to USB local printer?
I may be in the wrong department here, so feel free to move if needed: I am trying to use the LaserJet Cleaning Utility made for my HP LaserJet 5P (I know, it is an antique, but it still works!) connected via USB A to Centronics Parallel Printer Adapter. This utility consists mainly of two .PRN files, one of which you print about 3 copies, then turn the pages over so that the printed sides get re-fused and clean off the fuser rollers as they exit (they also use a LOT of toner, so that the HP guys make a lot of money!)
Problems are, the executable does not run in any compatibility mode for W10, the batch file doesn't work either.
Trying to simply send the file directly to printer has failed so far thusly:
copy hppass1.prn /B prncopy hppass1.prn /B USB001
copy hppass1.prn /b \\computername\printername
Now I know I have forgotten a lot of DOS and other command line syntax, but can anyone correct me here? I have even tried drag/drop the file onto the printer icon in Printers and Devices, and onto a shortcut to the same printer copied to desktop. No joy. What have I missed?
