If you are connecting via parallel port then you either need two parallel ports on your PC or an external switching box - approx £25, incl necessary leads. If you are connecting via USB (or one printer is parallel and one USB) then you don't need anything more than the spare ports on the PC to plug them into (or a USB expansion hub). Once both printers are installed, one of them will be set as the DEFAULT printer and every time you print something the PC will try to send it to that printer automatically. However, you get a chance to change your choice to the other printer via the Print dialogue box, so you have full choice between the two - IF they each have a separate port. If you use an external printer-sharing switch you would also have to manually switch to the selected printer to ensure your print commands are sent to the right one! Incidentally, this question should really have been popsted in the Helproom, where more of the 'techie' people would see it! Cheers. LC.
