The last time I did a full update and depclean seems to have removed the file
/usr/libexec/cups/filter/rastertopdf

This is causing failures when printing, depending on the setup of the printer (HP Colorlaser M255).

How do I fix this?

This file is owned by net-print/cups-filters. Did you remove that package?

I think it was removed by emerge --depclean, but then I reinstalled it.

Code:
equery files cups-filters | grep rasterto
/usr/libexec/cups/filter/rastertoescpx
/usr/libexec/cups/filter/rastertopclx
/usr/libexec/cups/filter/rastertops

# equery list cups-filters
 * Searching for cups-filters ...
[IP-] [  ] net-print/cups-filters-2.0.0-r1:0

# equery uses !$
equery uses cups-filters
[ Legend : U - final flag setting for installation]
[        : I - package is installed with flag     ]
[ Colors : set, unset                             ]
 * Found these USE flags for net-print/cups-filters-2.0.0-r1:
 U I
 + + foomatic : Build the included foomatic-rip printer driver. Strongly recommended.

# genlop -t cups-filters | tail

https://github.com/OpenPrinting/cups-filters/commit/0aad4d5bb6c8bb9d4ad72e93b18582811c8a6681

The filename was changed by upstream -- it is now called pwgtopdf since they decided it is more accurate to call it a pwg converter as it doesn't work with all raster inputs, but only the pwg variety.

Interestingly, it doesn't appear they ever actually mentioned this in the changelog for cups-filters 2.0.0.

If you have a custom printer driver that requires rastertopdf, you can simply edit it to use the new name.

I have had some success with restarting cupsd. This fixed issues on my Gentoo desktop. I should have done that before posting! Now, when printing from a Linux Mint desktop, I see the following on the server:
[code]
"cfFilterUniversal: Unsupported combination of input and output formats: application/vnd.cups-raster -> application/vnd.cups-pdf"
[code]
