USB to LPT3 with net use-goes thru queue, but doesn't print

Have a DOS app that can only print to LPT1 - LPT3. LPT1 is used by QuickBooks PDF Converter, LPT2 is mapped to a receipt printer on another computer, LPT3 was used by Intuit Internal Printer. I changed the internal printer to LPT1 so I could map LPT3 to the local USB printer, i.e. net use LPT3: \\computer\share /PERSISTANT:yes. It appears to work. In a cmd window, if I enter the following: type test.txt > lpt3, I can see it pass throug the correct print queue, but nothing prints. I can print other documents to that printer without any problems. There are no errors in the event logs.

The PC is a Dell Dimension running XP Pro SP3. The printer is a Canon MF4320 printer/copier/scanner/fax.

Anyone have an idea what the problem may be?

In the printer properties, is the print processor set to TEXT?

According to the spec sheet, the MF4320 supports something called "UFRII LT". I don't know what that language is, but I suspect it is a "host-based" language. Such printers rely on the Windows graphics engine to convert the page into dots on the paper. These printers do not understand text. Hence if you send them some text like the word "test", they usually do nothing at all.

This site actually says that UFRII LT uses the PC to "rasterise" the page. So it is a host-based machine, and you're out of luck with text.

hdhondt is right about the problem, and that I'll need another option. ded9 offered the other option. Will talk to client, and give PrintFil a try.

I don't know PrintFil, but DOSprn will also do the job of sending text to host-bsaed printers. See:
