Barry: Postscript is a computer programming language that is used by some laser printers as well as most high end imagesetters. It is either in ROM in the printer, or in a ROM cartridge inserted into the printer ( a cartridge that would plug into an HP LaserJet as an example). It's commonly called a Page Description Language, as it's mostly used for printing to Lasers. The difference between using a standard laser printer (or the DeskJet, or other dot matrix printer) is that Postscript (PS) printers are really computers dedicated to printing, and as such are intellegent devices, so they can do most of the "thinking" while the Amiga is then free to do other things. One of the major advantages are scalable fonts, that is you can have a font at ANY size you want, you're not limited to what your printer has, or to using Bitmapped fonts, or using CGfonts, and making the Amiga do all the work to figure out how to print the page. HP LaserJets are bitmaped devices just like the DeskJet, and the only difference between them is the physical method of printing (DJ sprays ink on the page, LJ uses a laser/drum/toner similiar to a plain paper copier). For DTP use in my opinion Postscript is the way to fly, and yes if you get a PS laser, you can specify how many copies to print, and the printer will print them out while you're doing something else with the Amiga. One way to see what Postscript output looks like to the printer is to save one of your files as Postscript, send it to a disk file, and then read the file with MORE or any other ascii file reader. This is the actual "program" that gets sent to a PS printer, and then the printer runs the program that makes your page. I hope I havn't confused you too much, but it's late, and I hope I didn't make this message hard to understand. -Mike Schiller In sunny Fort Lauderdale
