What is simplest solution for connecting 2 PCs to one printer where wireless isn't an option? Wondering about max length of USB printer cables, if ran around perimeter of room and if an A/B switch is definitely necessary? Have and HP 5100 series printer - wired w/ A/B USB cable to desktop - sits beside printer. A wireless upgrade kit is avail, but fairly expensive & read lots of users have problems. Wife's wireless laptop sits across small office from printer. Usually, she unplugs the cable from my desktop at the printer & plugs another cable from printer to laptop. She doesn't use the printer daily by any means. Thanks.
