Unless you use a toner-saving program to generate 'invisible holes' in bitmaps, I am unconvinced that printing at lower resolutions saves toner. A lower resolution of laser print will probably simply mean bigger dots and 150, 300 and 600 will still print a black square over the same area. How does this save toner? The greatest benefits of printing photos with a colour laser is that you can print on card which doesn't (can't) go soggy and stripey as inkjets can plus, a jpeg is sent to the PS printer for its routines to handle. If the gamma of the image is okay these often print very well and look better than the same image in a Sprite - which is converted to zillions of vector objects by the RISC OS printer drivers making files so big a PS printer -- Tim Hill of timil.com . . . * supports TFT & shares in cheaper ethical telecoms http://tjrh.eu/phone * has a genuine & spam-proof address for Usenet http://www.invalid.org.uk/ * accepts incoming email: substitute postmaster@ for tim@ ...
