After upgrading from RHEL 6 to CentOS 7 we have experienced problems with printing, it appears to have affected the font sizes and potentially also the margins. Printers are HP printers with a PostScript printer driver in place which hasn’t been modified as part of the upgrade.
How to Fix
This issue should be resolved in CentOS 7. A resolution for Rocky Linux 8 is still under investigation. Details can be found below.
|RHEL Version||Fixed in package||Erratum|

This can also be worked around by adding the following line to the CUPS configuration file (
SetEnv GS_FONTPATH /usr/share/fonts
After making the change, please restart CUPS so the change takes effect.
Origin of the Problem
Ghostscript is compiled with fontconfig support according to its help message, but ghostscript fails to actually use it. Therefore, gs only uses fonts available in the ghostscript font path. However, the ghostscript font path does not include
/usr/share/fonts. The fonts that ghostscript substitutes when it can’t find the correct font may result in misalignment and problems caused by incorrect font metrics.
