hp-ppd 0.9+nmu1 (riscv64 binary) in ubuntu oracular

 Because PostScript is just a page description language,
 there is a need to provide a mechanism for a print spooler to
 customize the PostScript Job to the actual printer device.
 .
 A PPD (PostScript Printer Definitions) specify the device specific
 PostScript commands needed to utilize printer features (such as
 printing quality, paper tray, duplex printing).
 .
 This package contains some PPDs for HP printers that are not in
 package linuxprinting.org-ppds
