I have a network consisting of an Intel iMac, an Intel Mac Mini, a G4 Cube, a MacBook and an Epson SC3000 printer all connected to a Netgear router, the MacBook wirelessly, and everything else through ethernet. I have an Epson R800 connected by USB to the iMac. On the Cube, I am using the Epson PPC drivers, and on the Intel Macs I am using the Epson Intel driver for the R800 and GutenPrint 5 for the SC3000, since Epson don't do an Intel driver for it. Printing from the Cube, I get good results from both printers, but every now and then the R800 driver seems to disappear. I will get a dialogue box saying that "Epson R800 cannot be found in your list of printers", which is patently untrue, as I can see it on the list. The only solution I have found is to reinstall the driver, whereupon I am informed that "A queue already exists for this printer". Printing from the Intel Macs, neither printer is useable for photos: they take forever to print an A4 sheet, and the colour fidelity is a sick joke. Lastly, I am not entirely sure how Printer Sharing works: I assume that the driver which runs the printer is the one on the machine one is printing from, not the one on the machine the printer is attached to. Is this correct? If so, how does the PPC Cube driver work through the Intel iMac?
