MINOLTA-QMS PRINTERS SUPPORT COMMON UNIX PRINTING METHODS.MINOLTA-QMS, Inc. has announced its support for the Common UNIX Printing System The Common Unix Printing System (CUPS) is a modular printing system for Unix-like computer operating systems that allows a computer to act as a print server. A computer running CUPS is a host that can accept print jobs from client computers, process them, and send them to , better known as "CUPS," as well as the PDQ (Parallel Data Query) A query optimized for massively parallel processors (MPPs). The software breaks down the query into pieces so that several parts of the database can be searched simultaneously. See SMP. printing system in its current color and monochrome network printers. Support for CUPS and PDQ widens the compatibility for MINOLTA-QMS printers to include all major versions of the popular UNIX UNIX Operating system for digital computers, developed by Ken Thompson of Bell Laboratories in 1969. It was initially designed for a single user (the name was a pun on the earlier operating system Multics). and Linux operating systems. "MINOLTA-QMS has always been a leader in UNIX printing," said Steve Fletcher, president and COO of MINOLTA-QMS, "Now, thanks to these innovative software solutions, we extend that leadership to include Linux printing as well. Our customers who use UNIX or Linux can now easily enjoy the efficiency of the Crown architecture built into our printers." Both the Common UNIX Printing System and PDQ allow MINOLTA-QMS to enable device-specific features, such as paper input trays or duplex printing options, by providing PostScript Printer Description PostScript Printer Description (PPD) files are created by vendors to describe the entire set of features and capabilities available for their PostScript printers. A PPD also contains the PostScript code (commands) used to invoke features for the print job. (PPD (1) (Parallel Presence Detect) The method used by earlier SIMM memory modules to communicate their capacity to the computer. A binary number coming from a parallel set of pins was read by the system, with each pin representing one bit. Contrast with SPD. ) files to the CUPS or PDQ environments. Customers who use UNIX or Linux applications can take advantage of either CUPS or PDQ to easily select these features through a familiar, web-based graphical user interface graphical user interface (GUI) Computer display format that allows the user to select commands, call up files, start programs, and do other routine tasks by using a mouse to point to pictorial symbols (icons) or lists of menu choices on the screen as opposed to having to . Both CUPS and PDQ were designed to alleviate printing problems encountered by users of UNIX and Linux. In these operating systems, generic printing is easy, but accessing device-specific features such as multiple paper input trays or addressable output bins is more difficult. The common printing methods now supported by MINOLTA-QMS printers break down barriers to printing by providing access to these device-specific features through graphical user interfaces or more conventional command line entries. According to the web site for CUPS (http://www.cups.org), "CUPS uses IPP (Internet Printing Protocol) A protocol for printing and managing print jobs over the Internet using HTTP. Initially conceived by Novell, Xerox and others, the IETF made it a standard in 2000 that includes authentication and encryption. See printing protocol and LPD. 1.1 to provide a complete, modern printing system for UNIX that can be extended to support new printers, devices, and protocols while providing compatibility with existing UNIX applications." PDQ differs from CUPS in its use of the LPD protocol within TCP/IP TCP/IP in full Transmission Control Protocol/Internet Protocol Standard Internet communications protocols that allow digital computers to communicate over long distances. . LPR/LPD is a familiar, but uncertain method of printing within UNIX. The web site for PDQ (http://pdq.sourceforge.net) states, "Most casual UNIX users regard lp and lpr as black holes into which print jobs disappear, and may or may not emerge. Most users print to the closest printer, and keep on submitting the job until they see it. A better model for printing is that the workstation processes everything, and submits finalized data to the printer when it first becomes available." Both CUPS and PDQ offer the UNIX and Linux user graphical interfaces as alternatives to the arcane command line prompt commands associated with printing in these systems. MINOLTA-QMS printer customers can now choose the printing environment they prefer when using either UNIX or Linux.
