The IBM 4245 is a high-speed impact printer that uses an engraved band. IBM proposed it as a replacement for the 1403, 3203 and the 3211/3811. As an example the Montana Department of Administration bought three 4245s (a model 12 and two model 20s) in October 1985 to replace two IBM 1403s and a 3211/3811. [21] [22] There are four consumable items:
The Honeywell Page Printing System (PPS) announced in 1974, is notable because it was the first commercially successful high speed non-impact printer. [1] It could produce output at up to 18,000 lines per minute, [2] where the earlier Xerox 1200 (the first commercially available electro-static printer) ran at 4000 lines per minute [3] and the contemporary IBM 3211 (which was an impact printer ...
During processing, IEBCOMPR compares each record from each data set, one by one. ... for the IBM 3211 printer, IBM 3800 laser printing subsystem and the IBM 4248 printer.
IBM defined two sets of printer commands, and therefore two sets of printer control characters are available. The first set of commands did not send any data to be printed to the printer but only a paper movement instruction. These are called immediate commands. The second set of commands send data to be printed on the current line plus a paper ...
Personal Printer Data Stream is a general name for a family of page description language used by IBM printers, which includes all Proprinter, Quietwriter, Quickwriter, LaserPrinter 4019, and LaserPrinter 4029 commands. PPDS was introduced to control printers in 1981 with the launch of IBM Graphics Printer 5152.
Later printers such as the IBM 3211 and IBM 4248 did away with the physical carriage control tape and used an electronic Forms Control Buffer (FCB) instead. ASA carriage control characters are still used for printer output from mainframe applications and software today.
Carriage control tape on an IBM 1403 printer. One channel punch is visible in this photo. A carriage control tape was a loop of punched tape that was used to synchronize rapid vertical page movement in most IBM and many other line printers from unit record days through the 1960s. The tape loop was as long as the length of a single page.
The term unit record equipment also refers to peripheral equipment attached to computers that reads or writes unit records, e.g., card readers, card punches, printers, MICR readers. IBM was the largest supplier of unit record equipment and this article largely reflects IBM practice and terminology.
