>As this seems to be at least partially biz connected, unless cashier and kitchen printer are really close to the computer, perhaps invest a few $ into an active USB cable. USB specs say 5m for USB2 IIRC, and often you can get away with longer lines - I had 7m USB cables to machine in dedicated room heated by computers alone and no real problems. But I was lucky as cable was running along/through wall and therefore out of sight and feet ;-)

>Running cables where there is no fear of accidents (to the cable of course...) is prudent if this is some kind of food outlet. Having even minimal problems with printing would cost more in time than an active, well placed extender cable (they extend range by factor of more than 7fold...) totally out of way. As at least some of those extenders work via CAT5 as intermediate cable type plus converters at both ends, you might also check if those printers could be turned into true LAN printers via LAN>>USB adapter sitting besides printer, but that might create printer driver problems. Still, anything in a different room is ***usually** better to connect via LAN than USB.

Of course, if we're talking about printers that could get shared on the network, it might make more sense to configure them as network printer (i.e. connect to server computer, a print server device, or use printer that you can plug into the network) rather than connecting them to workstation and trying to share them. Of course the hitch with this would be that this might mean a bit more of an involved process in installing the printer (e.g. using a printserver device or printer connected directly into network often requires you to deal dealing with network configuration items like TCP/IP addreses).
