I know basically nothing about font packaging.
I don't know whether or not other packages may
somehow depend on the ghostscript-fonts packages.
Perhaps ghostscript-fonts packages could be even removed?

Since a longer time Ghostscript
does not require any additional font package because
the PostScript standard fonts are included in Ghostscript.

- Do no longer require any fonts packages in particular
  neither require ghostscript-fonts-std because the PostScript
  Base35 fonts are provided by Ghostscript (in 'Resource')
  nor require ghostscript-fonts-other (provides Bitream Charter,
  Adobe Utopia, URW Antiqua, URW Grotesq and Hershey fonts where
  all but the last are also provided by texlive-<name>-fonts) and
  those fonts are not required for PostScript compliance, see
  https://bugzilla.opensuse.org/show_bug.cgi?id=1082896#c13
-----------------------------------------------------------------

Additionally there is in OBS Printing the package
urw-base35-fonts
https://build.opensuse.org/package/show/Printing/urw-base35-fonts

AFAICS this is about Type1 fonts. All fonts that are included in ghostscript-fonts-std are also available as TrueType fonts in ghostscript-fonts-std-converted and xorg-x11-fonts-converted.

Are there any applications that require Type1 fonts because they don't handle TrueType and/or OpenType? AFAICS only *real* legacy applications would. Even Adobe's own applications have ceased to support Type1 this year.

Perhaps Type1 fonts are still necessary for some old PostScript printers, but that doesn't justify installing them on every TW/Leap system.

On my TW system, the only packages with type1 fonts are ghostscript-fonts-std, texlive-lm-fonts and xorg-x11-fonts-legacy.

Btw, I would suggest renaming these packages such that "type1" appears in the package name. That would indicate to users why they might or might not want to have them, and would improve search results.

ok, just wanted to clarify it's not needed by ghostscript. Assigning to patterns-fonts maintainer then.
