Comment 1 for bug 691766

This looks like a PostScript printer with a buggy interpreter, where the best workaround is to use the printer in PCL mode.

Note that the CP2020 Series PPD file HP has designed for all HP Color LaserJet CP202x printers which are PostScript printers as they have the same PostScript interpreter and differ only in hardware features like extra trays, network connector, duplex unit, .... You could probably observe this problem also on an HP Color LaserJet CP2020.

Using the printer in PCL mode surrounds the printer's PostScript interpreter and the printer's PCL mode does not have this bug (or gets only raster data and so rendering fonts is moved to the responsibility of the computer).

As long as there is no fix by HP use the PCL driver which you have manually selected.

As a workaround, we can remove the PostScript PPD file from the HPLIP package so that for the printer only the PCL PPD file is found and so the PCL mode is used.

For investigation of the bug please do a printout using the CP2020 PostScript PPD file and which shows the problem.For this printout follow the instructions in the "error_log" and "Capturing print job data" sections in https://wiki.ubuntu.com/DebuggingPrintingProblems. Also attach the original file(s) which you have printed. Please attach the files one by one, do not package or compress them.
