To dump a screen from the QL to a printer, try this program. The escape codes are for the Brother HR5, but they work with most Epson-compatible printers. Although the program is written in SuperBasic, it performs at an adequate speed because it prints horizontally instead of vertically.

The routine only copies a screen area the same size as window 1. Line 170 works out which 16-bit word to look at. 180 bitwise ORs the two bytes to the red and green ones. In Mode 4, white red and green areas will become solid, in Mode 8, white and magenta will be solid, the rest of the colours being shaded.
