We are using system 6.0.5, with the LaserWriter driver 6.0.1 and printing to a LaserWriter Plus. When we sent color PICTs to the printer, with the Color/Grayscale option set, the printout is in black and white, no grayscale. Is anybody out there having the same problem? What's the deal? We tried printing from several applications (ResEdit, Word, PictViewer). Is this feature application dependent? And yes, 32-bit Color Quickdraw was installed and we tried from an SE and aSE30.

There is no way to change this except get a new printer. B/W refers to any printer that has just black print capability, including the laserwriters that render greys by halftoning. You will never get continuous tone greys out of the LaserWriter series. Color/Grey is used for color printers and continuous tone greyscale printers. The difference is that halftone processing is not done on the Mac, but instead allowed to pass to the printer. With B/W checked, the Mac does simple halftone preprocessing of solid regions. Bitmap images are still halftoned in the PostScript engine, which is why printing bitmaps takes longer than you would think it should. You should only check the Color/Grey option if you have a color printer or a printer capable of continous tone printing. Currently, the only printers capable of continuous tone greyscale printing that I know of are Dupont's 4cast, one by Mitsubishi, and two by Kodak. The Kodak ones can only be printed to from Adobe PhotoShop via a plug-in module, so the LaserWriter driver is not a concern. Kodak is writing their own chooser driver and PostScript RIP which should be out at the end of the year. If any PostScript gurus (Amanda, Woody?) want to correct me, or if anyone knows of other continuous tone printers, please e-mail or post. Paul Eric Menchen menchen@grad1.cis.upenn.edu

Well I'm not a PostScript guru; I just print photos using the color/gray option on an ordinary 300 dpi QMS laser printer. The difference between black/white and color/gray options is close to the difference between a monochrome and grayscale monitor. I can now print photos from Word instead of having to use PageMaker.
