LPT5 does simply not exist -- and I wouldn't know which parallel > port it would use from DOS' point of view... I probably asked my question poorly. I don't really want more "ports" (as in hardware ports), what I need are more printers (but DOS only knows about them as LPTx). And most of them would be network printers. So I guess what I'm looking for is a way to have the DOS app see more LPT ports and have them redirected to a real printer on a server somewhere. > If the printer works like a file then you could just try to link to it on > an lredir'ed drive in Linux (printer would be d:\printer.foo or something > like that). I didn't understand this part, could you elaborate a bit. Thanks, Michael
