This more than positive appraisal is the result of the very important contribution and the responses of Ricoh to questions of Linux users on the site LinuxPrinting.org!
LinuxPrinting.org is an 'open source' Internet site aimed at users who print especially by means of Linux.
Ricoh PPD (PostScript Printer Description) files provide unequalled functionalities under Linux (protected print, PCL driver, etc) for its range of multifuntional devices and printers.
