Technitron Data Ltd, the Slough-based UK distributor for Oki Electric Industrial Co, has announced two new Hewlett-Packard LaserJet II compatible printers, the OkiLaser 400 and 800, which despite the name have nothing to do with lasers: using Light Emitting Diodes as the initial light source, the OkiLaser 400 and 800 are claimed significantly to reduce running costs and increase reliability by avoiding the moving parts, such as mirrors, required by laser printers. The four page-per-minute 300dpi resolution OkiLaser 400, with the basic 512Kb of memory, takes 1Mb upgrades up to 2.5Mb; Technitron says the 400, which like the 800 incorporates an engine built in-house, is aimed at a number of low to mid-range applications such as word processing with some desktop publishing. It handles A4, A5, B5, A6 and envelope sizes from a 200 sheet input tray, with face up and face down output, and has 25 resident fonts, one font slot and six font cartridges. With all running costs included, Technitron says users will pay an estimated 2.8p per page. Available with either parallel or serial interfaces, prices start at UKP1,250 for the 512Kb version, with the memory upgrades, fitted by approved dealers, working out at an extra UKP280 per Mb. Specifications for the eight-page per minute OkiLaser 800 are basically the same, with various enhancements: apart from LaserJet Series II emulation, IBM Proprinter and Diablo 630 are also accommodated, and there are 35 resident fonts; single and dual bin options are available, and memory can be expanded up to 4.5Mb; prices start at UKP1,800 for the single bin version, UKP2,000 for the dual bin, with memory expansion costing the same as for the four-page printer; the OkiLaser 400 will be available from mid-November, with the 800 following in January of next year.
