I realize this entry stretches your rules a bit. So many screen utilities have been published for the ZX81 that it would seem difficult to come up with something completely original. Therefore, my entry, while very much a “Display Utility” and my own creation, addresses a specific challenge inherent in a very popular hardware add-on. My PRTSC Utility uses the ZX ROM character generator to copy the screen as you see it to any EPSON-workalike printer via the MEMOPAK Centronics I/F. Documentation covers modifying the program to work with printers which use non-standard graphics escape codes.
