Wang printer exploits fiber optic technology
Combining CRT and fiber optic technology with a plain paper, dry toner copying process, the intelligent Image Printer offers a high output rate together with typewritten document quality, according to Wang Laboratories.
The Image Printer's principal operational features include an output rate of 18 pages per minute, varied font selection, concurrent multi-user access, high resolution fonts, and dual-mode operation.
Varied font selection permits mixing of type styles and sizes, and combined vertical and horizontal (portrait and landscape) printing functions within one print run. Three type styles are supported online with additional fonts available.
Concurrent multiuser access makes the printer an output device sharable by as many as 24 word processing operators. Linked on-line to a Wang Office Informal tion System/130 or 140, or to one of Wang's other computers, an Image Printer can queue multiple printing jobs while operators continue with other work.
High resolution fonts result from character images formed with 90,000 dots per square inch precision. Made possible by the CRT/fiber optics system,this resolution suggests that languages previously unsuited to automatic printing can easily be incorporated into Image Printer font libraries, says Wang.
Dual-mode operation permits the printer to operate as an of flee copier as well as an output device. In the copier mode, the Image Printer produces nine copies per minute. But Wang adds that the printer should eliminate much of the need for of" fice copying, as an operator can use the device to print multiple copies faster than he can type one master and make copies from it.
In use, a document is originated on Wang OIS/130 or 140, or other Wang come puter system. The operator uses standard word or data processing computer tech" niques to key and/or edit the document.
The completed document is then stored on disk until a print request is made.
When a print request is originated, the document is transferred from disk through a data channel to the Image Printer's microprocessor control unit. The control unit assigns the print commands and selects the font and type sizes specified by the operator. A character generator then converts the digitized document into precise visual images that are displayed, a line at a time, on a CRT located inside the printer. As each full line is displayed, the printer s electronics scan
