360 CHAPTER 9: INSTALLING DEVICESPrinterConfigurationOverviewThe VCX operating system includes the Common Unix Printing System(CUPS) for printing support in IP Messaging. This support enables IPMessaging to automatically send faxes to a printer. Fax auto-delivery isdescribed in the IP Messaging Operations and System AdministrationGuide.This appendix describes how to set up a default printer. For moreinformation on printer configuration, refer to one of the followingresources:■ CUPS documentation — On your VCX or IP Messaging system, accessthe /usr/share/doc/cups-1.1.17 directory. This directory containsseveral documents in PDF format, including the CUPS SoftwareAdministrator’s Manual (filename: sam.pdf). This manual providesextensive information on printing.■ CUPS web page — The web page, http://www.cups.org, also includesextensive information on CUPS.■ Man page — Enter the command man lpadmin for a quick referenceto printer configuration.Adding a Printer The VCX operating system uses the lpadmin interface for printer setup.This interface is the standard command line tool for configuring CUPS.Note that you must be logged in as root to execute these commands. Thedefault password for the root account is pvadmin.CAUTION: 3Com strongly recommends that customers change thispassword on all VCX servers. Guidelines about other passwords and othersecurity-related issues can be found in the “VCX Security Guide.”The following commands set up a remote PostScript printer./usr/sbin/lpadmin -p myPrinter -v lpd://10.1.1.1/lp -mpostscript/usr/bin/enable myPrinter/usr/sbin/accept myPrinterThe first command identifies name of the printer as myPrinter and thename of the printer queue as lp. The printer’s IP address is 10.1.1.1.
