>penguin would shrink the result to fit its screen. >I declared A5 and Letter paper, media type stationery, and an output bin called face-up. You can (and should!) define exact dimensions of your screen in `media-size-supported`. It will probably be a non-standard IPP name, that's why you should define that in `media-supported` as `om_NNNmmxYYYmm` or `oe_NNNinxYYYin` That way you don't need to scale the incoming data, the PC will format it exactly to the dimensions of the screen. Both PWG Raster and Apple Raster support 1-bit-per-pixel mode (instead of 8-bit-per-pixel you use), that's why the input could be 8 times less in size. Use `print-color-mode-{supported,default}=bi-level` instead of `monochrome` for that. And also tune `urf-supported`'s `W` option, use `W1` for this case. The screen/dithering could be ass in 1-bit mode, see https:

Please consider adding this and possibly other algorithms to CUPS printing system. Easiest is to add it into ghostscript. https://github.com/OpenPrinting/libcupsfilters/pull/92
