Steve, The GIF format does a really good job of compressing graphics, and a small GIF file could represent a really large image at high resolution. In the printer the image is expanded to an uncompressed raster image. I've found HP laser printers seem to be optimized for text, and (particularly Postscript printers) are slow, and often run out of memory, with graphics. Quite often I've found my HP1300 (a postscript laser printer) dies after working for ten minutes on an image which prints in a couple of minutes with an inkjet printer (which uses Ghostscript to send the image to the printer a little at a time). But the HP1300 runs rings around the inkjet on text. Les
