The 4550 automatically senses Epson LQ code and turns on emulation. It is like if the DIP switch were set to automatic in older BJC models. ---------------------------- By: Jim Stafford My Canon BJ 600 works fine with the above driver. The only thing the driver doesn't do is color!!! Make sure you have the epson dip switch set on your printer(see the manual). ---------------------------- By: Joe Kohn I know for a fact that Harmonie supports HP LaserJets, DeskJets, and DeskWriters. Tony Diaz (of Alltech Electronics) brought home an Epson Stylus 600 and connected it to the IIGS. Of all things, the first thing he tried was Print Shop GS, and he said it printed out beautifully, in full living color. The margins were all correct, and everything else about it was right...using the PSGS Epson LQ driver. He was also able to output text at 360 x 360 from EgoEd, using Harmonie's Epson LQ4000 driver; and, he could dump text to the printer with a PR#1 from the Applesoft prompt. So, apparently these Epson Stylus printers do have internal fonts and can be used from ProDOS-8. Tony was able to print out a graphic from Platinum Paint at 360 dpi; but, only in grayscale. In Fact, so far, everyone reports that they can print in full glorious color from Print Shop GS, but that, when printing from GS/OS via Harmonie's EpsonLQ drivers, the printout is limited to grayscale.
