Ansible Role: cups

Installs CUPS, installs necessary PPDs and installs printers and classes on CUPS

Install and configure CUPS

• Installs cups and cups-pdf
• Accounts defined in cups_lpadmin_users will be added to lpadmin group to administrate CUPS.
• Installs cups-lpd if variables allow (see below):
  • Creates a user account which will run the cups-lpd process.
  • Installs xinetd to run cups-lpd as a service. Uses the cups-lpd template file to create the final xinetd config.
• Configuring CUPS:
  • If templates for cupsd.conf, cups-browsed.conf and snmp.conf are provided they'll be built and copied over
  • If SSL certs are provided it'll copy them over to the proper location.

Install PPDs

• Creates /opt/share/ppd where CUPS looks for PPDs that are manually copied over.
• Adds OpenPrinting Repo.
• Install Ricoh OpenPrinting Package - openprinting-ppds-postscript-ricoh
  • Also unzip the PPDs it installs as the package installs them as gzip files in /opt/OpenPrinting-Ricoh/ppds/Ricoh
• Installs HPLIP:
  • Also installs the HP proprietary plugin using an except script.
• Copies over PPDs from the folder if specified in cups_ppd_files_to_be_copied to /opt/share/ppd

Install Printers

• Any printers defined to be removed will be removed first.
• Install Printers listed in the cups_printer_list variable and then installs classes listed in the cups_class_list
  • See cups_printer_list and cups_class_list to see how to define each printer and class object in the variable cups_printer_list and cups_class_list respectively.
  • This uses the cups_lpadmin module. There's documentation/comments within it on how it can be used.
  • cups_lpadmin is a direct copy from HP41.ansible-modules-extra/system/cups_lpadmin. Once it's merged upstream, it'll be removed from here.
