In 1990 Computer Concepts saw that the ARM2 was one of the fastest CPUs around and that the Archimedes could have enough memory (ca. 2MB) to hold the bitmap page images. The result was the LaserDirect which did away with the laser printers CPU and memory and drove the printing mechanism directly from the Archimedes using the ARM CPU and its memory. The first LaserDirect printer was based on the Qume CrystalPrint page printer, see QUME on the right had side of the first picture. Risc User magazine estimated that it was 30-50% faster than the normal Qume printer and 4 to 5 times faster than a dot matrix type printer. Later Computer Concepts developed a version using the Canon LBP-4 and LBP-8 printer engine. Unfortunate a Laser Direct podule is not much use now unless you still have the LaserDirect printer in working order. Here is the Computer Concepts LaserDirect manual (for a Qume printer).
