How to send .prn file directly to USB local printer?


Just to be sure I am on the right track:










Using these names, I get the following:






Am I missing something obvious?
Does the USB/Parallel Printer adapter cable make this a problem?
Does file and printer sharing have to be enabled to copy to a local printer?

 

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 prn
copy 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?

 

PRN file in C#

C# questions are beyond the scope of this consumer-oriented peer support forum.

It's not clear what you mean by "print ... as a label," but *.prn files -- in Windows at least -- are the raw output files (including printer control characters) from Windows printer drivers.

In Windows, you print a *.prn file by doing a binary copy to the printer, which must be the same model as the printer driver that produced the *.prn file.

The following is based on
Bruce's Printing Pages

1. If the printer is connected to a port that the Command Interpreter (Command Prompt) can access (e.g., LPT1 then from a Command Prompt

copy /b file.prn LPT1:

2. If the printer is connected by USB (which is not accessible from Command Prompt), share the printer and from a Command Prompt

copy /b file.prn \\servername\sharename

or you can map the share to an LPTn port and then use method 1

net use LPT1: \\servername\sharename /persistent=yes

copy /b file.prn LPT1:
