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 ...
Many of these programs were designed by IBM users, through the group SHARE, and then modified or extended by IBM from versions originally written by a user. These programs are usually invoked via Job Control Language (JCL). They tend to use common JCL DD identifiers (in the OS, now z/OS operating systems) for their data sets:
Generally, these printers are at the medium to the high end of the print speed and volume spectrum. "One of the strengths of IPDS is that independent applications can create source data for each data block. The output of these independent applications is merged at the printer to create an integrated mixed data page." [2]
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.
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 ...
The Diagnose instruction ('83'x—no mnemonic) is a privileged instruction originally intended by IBM to perform "built-in diagnostic functions, or other model-dependent functions." [ 14 ] IBM repurposed DIAG for "communication between a virtual machine and CP."
This is the bi-directional protocol used between the host server and the printer. It is used to send the page-level data to the printer and to signal errors and accounting information back to the server. The IPDS protocol also allows the server to query a printer's available resources (e.g. available memory, fonts, input trays, etc.).
