|Most if not all USB to parallel port adapters, that have the proper appropriate circuits between the two connectors, work fine with parallel printers, but often they do NOT work fine with other devices that use a parallel port connection, such as scanners, and the scanner component of an all in one. Read the description of what the device can do in it's ad, or better still, read the info on the manufacturer's web site for the model. If you find an ad on a site that has user reviews available also, read those too. E.g. Newegg, TigerDirect. |
Parallel port cards, on the other hand, should work fine with anyrthing parallel port connected.
PCI parallel port cards are still avaiable on the web, but you may not find one locally. As far as I have seen, they are always enhanced parallel port cards these days - their chipset supports EPP and/or ECP mode, which most parallel port connected devices require.
NOTE that the Lava parallel port card I tried does NOT get along with older Sound Blaster (Creative) sound cards, or SB (Creative) sound chipsets on mboards, such as ISA SB16 cards/chipsets - the chipset produces no sound when the Lava card is installed - there is no fix - and that may apply to other SB chipsets and other chipsets that emulate SB legacy support.
A few more recent mboards have no parallel port built in but they do have a header for one you can connect a ribbon cable and port to. See the mboard's manual.
