|If you mean the computers are all connected on the LAN via a network hub/switch box, set up a local network on each computer you want to be be able to use the printer and enable file and printer sharing while doing that. When all the computers are on, in a short time, but not instantly, the necessary drivers will be copied over the network to each computer and the printer model will automatically appear as a network printer in Control Panel - Printers and Faxes.|
I'm assuming all the computers have 2000 or XP on them. If any have ME or previous, the procedure on those computers is different and I know from previous experience that you can't have some models of HP printers shared as a network printer unless all the computers areusing 2000 or XP.
If any computers have Vista or Windows 7 on them, the printer may or may not appear automatically as a network printer on those computers when you have enabled file and printer sharing.
