Printing from Chromebook
Chromebook runs applications through the Chrome OS which adopts the Common Unix Printing System (CUPS) for printing. CUPS requires a PPD format file to change the print settings.
To print from Chromebook, RICOH provides PPD files and asks Google to bundle them with the Chrome OS. By installing PPD files, users can print from Chromebook with RICOH products.
Google also provides a printing system called Google Cloud Print to print from Chromebook.
After Google ends support for Google Cloud Print (as of December 31, 2020), Google recommends printing with CUPS as an alternative.
Chrome OS 86.0.4240.77 or later.
