I have two computers connected to an ieee 1284 compliant belkin auto-switcher, using ieee 1284 parallel cables.(there is a 9v power pack connected to the auto switcher to boost performance) The switcher is then connected to a manual 4 device belkin ieee 1284 switch box. There are three devices connected to the manual switcher, a quickcam, hp 722c printer and an avecII e330 scanner. Both computers can use the camera and printer with full bi-directional function. However the scanner only functions correctly from time to time. If I plug the scanner directly into either computers parallel port it functions perfectly every time. I do not have a spare ISA slot for a second parallel port card and don't want to invest in a true network setup. Do they make pci parallel port cards? Or is there some other trick to get this setup to work correctly with the scanner?
