Hollywood, MD (September 13, 2004) -- Easy Software Productstoday announced the 1.1.21 release of the Common UNIX PrintingSystem ("CUPS"), an IPP/1.1-based printing system forUNIXCUPS 1.1.21 is primarily a bug fix and performance tuningrelease and includes fixes for the IPP, LPD, parallel, serial,and USB backends, authentication and status processing issues inthe CUPS API, and various PostScript and PDF printing issues.The new release also adds support for Zebra label printers andIPP device URI options. CUPS is available at: provides a portable printing layer for UNIX-basedoperating systems. It has been developed byEasy Software Products topromote a standard printing solution for all UNIX vendors andusers. CUPS provides the System V and Berkeley command-lineinterfaces.CUPS uses the Internet Printing Protocol ("IPP") as the basisfor managing print jobs and queues. The Line Printer Daemon("LPD") Server Message Block ("SMB"), and AppSocket (a.k.a.JetDirect) protocols are also supported with reducedfunctionality. CUPS adds network printer browsing and PostScriptPrinter Description ("PPD") based printing options to supportreal-world printing under UNIX.CUPS includes an image file RIP that supports printing of imagefiles to non-PostScript printers. A customized version of GNUGhostscript 7.07 for CUPS called ESP Ghostscript is availableseparately to support printing of PostScript files within theCUPS driver framework. Sample drivers for Dymo, EPSON, HP, andOKIDATA printers are included that use these filters.Drivers for thousands of printers are provided with our ESPPrint Pro software, available at: is licensed under the GNU General Public License and GNULibrary General Public License. Please contactEasy Software Products forcommercial support and "binary distribution" rights.Changes in CUPS v1.1.21:- The scheduler did not separate Digest authentication parameters with commas (Issue #882) - Fixed some problems with image printing to custom page sizes (Issue #891) - Removed the remaining scheduler code that did not use the "close-on-exec" file descriptor flag to speed up program invocations (Issue #890) - The "lpr -r" command removed the print file even if it was not printed. It now only removes the file if the job is successfully created (Issue #886) - Revamped the custom page size orientation fix (Issue #127) - The lp, lpq, lpr, and lpstat commands now report when an environment variable is pointing to a non-existent printer instead of just saying "no default destination" (Issue #879) - Queue names with 2 periods (e.g. "printer..2") were not supported (Issue #866)
