I'm doing some relatively weighty printing at home at the moment and I have two Epson printers (a DX7450 and a P50). Both are connected to an iMac running OS 10.5.8 via separate USB ports. I have tried setting up to run to both printers at once but it will only allow me to run either one at a time. I'm using the standard Epson drivers and software for each one - any ideas? Thanks in advance...
