Printing on all CAL CWs is accomplished without a centralized print server. All CWs print directly to the networked printers.

Please review CAL Subversion Repository and Package Management/SVN Configuration information before proceeding.

• Checkout the necessary branch of the current svn repository:

  svn co https://docs.astro.columbia.edu/svn/cal-svn/trunk/packages/cal-meta
  

• Update the printers.conf file with the new printer configuraton:

  emacs /src/cal-meta/src/cal-configured-workstation-config/etc/cups/printers.conf
  

• Create the ppd file on a CW or local test machine.

  Use the System > Administration > Printing > New Printer menus
  to create the ppd.
  

• Transfer the printers.conf and ppd file to a CW for testing.

  Use GSSAPI Authentication:
  
  ssh -oGSSAPIAuthentication=yes root@
  
  scp printers.conf root@CW:/etc/cups
  
  scp printer.ppd root@CW:/etc/cups/ppd
  

• Test the printer setup before distributing the changes to all of the CWs.

• Distribute the changes to all of the printers:

  Issue the following commmands to verify changes to checked-out files:{{{
  
      svn status
      svn diff 
      svn rm 'printer'.ppd (use this command only if removing a printer and after modifying the printers.conf)
      svn committ /src/cal-meta/src/cal-configured-workstation-config/ (updates the CAL Repository)
      
   * place detailed comments regarding modifications in the 'changelog'
