400-lpm line printer offers ruggedness, graphics too

Hewlett-Packard claims a new high in ruggedness, based on more than three machine-years of life testing prior to production introduction, for its new dotmatrix, 400-lpm line printer. The printer uses a virtually frictionless print mechanism under the control of a microprocessor that provides self-diagnostics, improves operating speed, and makes possible a variety of character and graphic print modes.

The 2608A printer can be programmed to produce characters of double normal size. Quality is preserved by doubling the normal 5 x 7 matrix to 10 x 14, according to l IP. As many as 16 different character sets can reside within the printer, and any two may be used within any line. The standard set is 128-character US ASCII. Options include Cyrillic, Katakana, APL, and most European sets.

Under program control, the 2608A can plot any graphic display that can be

~_ _ , a. _ , . _ _ . _ _

described by a matrix of dots with a density of 781 dots per square centimeter 15040 dots per square inch). These are placed with 0.03-mm (0.014-inch accuracy, yet a 30-cm (12- inch} page can be printed in less than 20 seconds.

The basic print mechanism uses a print hammer and drive coil for each of 132 character positions. Each hammer, under microprocessor control, strikes the page with equal impact, producing characters and graphics free of ghosts, smears, light, or missing areas. The HP 2608A will print the 64- character ASCII set at 400 Ipm, with a vertical slew rate of 14 ips and a 16-channel vertical format control.

Self-test, initiated with a control switch or under program control, verifies operational status automatically. Should failure occur, fault registers identify in a binary display the specific portion of the routine that is involved.

(Image Omitted: US price of the HP 2608A impact line printer is $9250; an optional sound cover is
