When I bought the mac, a couple of years ago, I installed an epson R200 and a 4880. I also installed my Mitsubishi dye-sub. I had problems from day one, and could only get 2 of the 3 working at one time. Uninstall/reinstall mess around etc, etc. I have forgotten the process exactly. Anyway, I gave up altogether & priorities to the 4880 & dyesub. All printers are installed via USB, not network. I have been running the R200 on an old PC, but that has now broken down & I have now acquired a canon iP4200. That is currently installed on the PC & is fantastic. HOWEVER, In an ideal world, I would like to run it via my mac. Both 4880 & dyesub are working fine, and the 4880 in particular has a huge amount of personal settings. ......THEREFORE, my dilemma.....Do I install the canon & hope all 3 work or continue to use it on the PC. All of my documents are designed on the mac & then transferred over to the PC, but inevitably there are always little niggles with file (.docx) compatibility (fonts etc) between pc & mac. Has the mac any limitation on the number of printers it runs? Can anybody shed light on why one 2 printers work at any given time? I had experienced the same proplem to, with a xerox lazer.
