I have been trying net use lpt1: \\computer\printer to redirect my DOS app to my USB printer. I do not have a parallel port. Sometimes (sometimes not)I can print from the command line (e.g. DIR > LPT1:) of the DOS window but never from my app.
net use lpt1: has always worked in XP etc.

Thanks for any input

Arnold F

Did you launch your command prompt as Administrator? Also, is the printer configured as a shared device?

I'm not running Vista and I well know the way you use to redirect a LPT port to USB.

So, please, how are you running your legacy application under Vista? As I assumed Vista doesn't allow any more 16 bit applications but inside a Virtual Machine. In Xp on the contrary they are handled by the command prompt via NTVDM integrated emulator.

Your info may help to look more accurately at your issue.

I am not doing anything special. I am running 32 bit Vista and my app (written in MS Quickbasic) runs perfectly in a Vista DOS Window except for the redirecting LPT1 problem.

Arnold,
that's a known problem for DOS programs running on Vista (and yes, Vista 32, unlike 64, still allows running DOS programs)
You may want to have a look at Printfil to capture and redirect your DOS print jobs in Vista. More info and a free trial version is available at http://www.printfil.com
