Xerox Corp has expanded its range of high-speed mainframe printers from its Printing Systems base in El Segundo, California with the introduction of the Xerox 4075 Computer Printing System. The ion deposition printer can produce output with a variety of forms, type fonts, logos and signatures, which are electronically stored as graphic elements for automatically merging with variable data from the computer, speeding operation by eliminating the need to receive forms and fonts with the variable data. Unlike a laser printer, instead of creating an image with a laser beam, the 4075 deposits ions – charged particles – onto a rotating drum and these attract toner from a bin in the printer. The 4075 prints 240 dots per inch, at the low end of the resolution offered by laser printers, and is rated for 800,000 pages a month, using standard 8.5 by 11 cut sheet paper. A single page can include up to 16 different type styles out of a library of more than 200 fonts. The single-unit base price of the Xerox 4075 with a 10Mb hard disk, is $64,495. Adding a 45Mb disk costs $2,000, and the new printer is available now in the US.
