compatibility was well regarded, although limitations were noted around paper handling and emulations of other kinds of printers. An upgrade board was also available to give Qume CrystalPrint Series II printers PostScript compatibility. Subsequent models in the range included the CrystalPrint Publisher II, featuring improved paper handling over its predecessor, and CrystalPrint Express, a network printer with 3 MB of RAM supplied and a resolution. The CrystalPrint engine was itself used in the Computer Concepts LaserDirect printer, announced in 1990 at a price of £1148, aimed at the Acorn Archimedes range of computers. This printer was driven directly by the host computer in conjunction with an expansion card, eliminating various costs associated with conventional laser printers, specifically the hardware and software responsible for page rendering (leaving "the bare minimum of circuitry in the printer"), and took advantage of the Archimedes' ARM processor to deliver competitive printing performance, albeit requiring the host computer to hold the image of each page in its own memory. A RISC OS compatible printer driver combined with Acorn's outline font format permitted a single set of scalable fonts to be used for both screen and printer use. Calligraph's ArcLaser product, launched at around the same time, was broadly similar, and both products were regarded as "offering faster-than-Postscript speed for less-than-laserjet price".
