CUPS 2.0.2 发布，此版本现已提供在：http://www.cups.org/software.php。 此版本修复了一个潜在的缓冲溢出问题，还有一些常规的 bug 修复： •Security: cupsRasterReadPixels buffer overflow with invalid page header and compressed raster data (STR #4551) •Command-line programs were not localized on Mac OS X (<rdar://problem/14546232>) •The scheduler incorrectly cleared the MakeModel string in the printers.conf file after a restart (<rdar://problem/16827518>) •CUPS did not compile with older versions of GNU TLS (STR #4527) •CUPS did not compile without Avahi or mDNSResponder (STR #4523) •ippLength() did not return the correct length for IPP_TAG_CONST string values. •The scheduler incorrectly aborted jobs after a job was restarted (<rdar://problem/19129387>) •The cups-files.conf file contained the old ServerCertificate/Key directives instead of ServerKeychain. •Fixed builds when no SSL/TLS library is available, or when explicitly disabled (STR #4531) •Fixed an OpenBSD charset transcoding issue. •Fixed USB printing on OpenBSD (STR #4525) •The --without-xinetd configure option did not work (STR #4542) •Backends needing to load OS X kernel extensions did not work (<rdar://problem/19015679>) •Mapping of PPD keywords to IPP keywords did not work if the PPD keyword was already an IPP keyword (<rdar://problem/19121005>) •cupsGetPPD* sent bad requests (STR #4567) •ippserver used the wrong temporary directory on Windows (STR #4547) •ippserver did not handle Bonjour registrations properly (STR #4548) •The scheduler could crash during shutdown if Avahi was shutdown first (STR #4550) •Added a USB quirk rule for Intermec printers (STR #4553) •The scheduler did not always log which configuration file had the error (STR #4559) •The ippfind and ipptool programs now correctly match hostnames with trailing dots (STR #4563) •The ipptool timeout option did not work (STR #4515) •Fixed several issues with client.conf, CUPS_SERVER, and the "-h" option of most commands (STR #4528) •Another change for OpenBSD (STR #4526) •Added Japanese localization (STR #4524) •Documentation changes (STR #4569) Enjoy! Unix/Linux下打印总是有许多限制。但若安装了CUPS（Common UNIX Printing System），你将会得到一个完整的打印解决方案。 在UNIX/Linux 下打印的方法很久以来都是用lpd（命令行方式的打印守护程序），它不支持IPP（Internet打印协议），而且也不支持同时使用多个打印设备。 CUPS给Unix/Linux用户提供了一种可靠有效的方法来管理打印。它支持IPP，并提供了LPD，SMB（服务消息块，如配置为微软WINDOWS的打印机）、JetDirect等接口。CUPS还可以浏览网络打印机。 (责任编辑：IT) |
