+ 0 Votes I might try.. bart777 6 years ago Using a print server device. Ussually their pretty cheap and will allow you to connect either via usb or network. + 0 Votes As Thumbs mentioned w2ktechman 6 years ago parallel to USB sometimes works well, other times it doesnt work. I have run into several printer types that I just couldnt get working with it. As Bart mentioned, for these instances, a Print Server should work just fine. I prefer IP based myself. + 0 Votes Conrtact HP mjd420nova 6 years ago I would try and see if HP has an updated driver for the VISTA OS. Otherwise the above answer would or should allow use. I use a router with a parellel port to support my old parellel printer. This then gives everyone on the network access to the printer too. + 0 Votes LPT1, LPT2, etc...... ThumbsUp2 6 years ago Look at the printer and see if it is set to the LPT1 port, then look at the adapter and see if it has set itself up as LPT2. The printer must be using the correct port to find communication. However, not all devices, especially OLD printers, are capable of communicating through a USB adapter. Some of them depend on IRQ's/DMA's and other settings which don't necessarily get assigned to the USB adapter. Read the specifications required for that printer to see if it NEEDS something the adapter is not providing.
