libppd-dev 2:2.0~b2-0ubuntu7 (riscv64 binary) in ubuntu lunar

 This library contains everything needed to support PPD (PostScript
 Printer Description) files, reading and parsing, handling collections
 of PPD files, building PPD files from printer IPP attributes and from
 *.drv files.
 .
 It contains the full PPD file and PostScript output functionality of
 CUPS 2.x (libcups, ppdc) and cups-filters 1.x, so that the functionality
 stays available for retro-fitting classic CUPS drivers after switching
 to CUPS 3.x which has all PPD file support removed.
 .
 This library contains filter functions doing all kinds of file format
 conversion used for printing and scanning, to be used in Printer
 Applications, CUPS filters, printer drivers, ... also other commonly
 used functions for handling print data, like color space/depth
 conversion, dithering, IPP message parsing, ... are available.
 .
 This package contains the header files to develop applications (Printer
 Applications, CUPS filters, printer drivers) using libppd.
