The printer installation fails when you install a printer through IPP or the command line utility.
Unable to install the printer when the specified PPD file is not found
When you install a printer, the iPrint Client verifies the availability of the filters specified in the PPD file. If the filters are not available, the printer installation fails.
Search for a CUPS-compatible driver for the printer that failed to install. Use the /usr/bin/cupstestppd utility to verify if the PPD is supported by CUPS.
