The Ricoh copy machine that currently sits near Rebekah does not include the Adobe PostScript 3 module. Native printing to this machine is not supported on Mac OS X. Installing a set of third party tools will allow printing to the machine using unsupported drivers.


  • Install the Foomatic-RIP pkg
  • Install the GhostScript (gplgs) mpkg
  • Install the PXLMono pkg
  • Install the printer using the new PXL drivers


Yosemite (10.10) and above note:

With the introduction of sandboxing in Yosemite, it is now necessary to modify the PPDs installed from PXLMono. Run the yosemite_foomatic_paths.command script as root to make the changes and allow printing.

  • Run yosemite_foomatic_paths.command as root


El Capitan (10.11) and above note:

El Capitan introduced System Integrity Protection. This will actively protect a number of system folders from being modified by anyone, including root. The GhostScript mpkg makes changes to the directory /usr/libexec/, which is protected under SIP. Additionally, it seems that mpkg files have been deprecated so the GhostScript mpkg will fail to install anyway.

Disable SIP
  • Restart into Recovery partition
  • Terminal >> csrutil disable
  • Terminal >> shutdown -r now
Proceed with installation
  • Install the Foomatic-RIP pkg
  • Right-click the GhostScript installer mpkg and choose Show Package Contents
    • Navigate to Contents/Packages and install each pkg individually
  • Install the PXLMono pkg
  • Install the printer using the new PXL drivers
  • Run yosemite_foomatic_paths.command as root


Re-Enable SIP

  • Restart into Recovery partition
  • Terminal >> csrutil enable
  • Terminal >> shutdown -r now
