For users who have Gentoo installed and are using cups for printing, if attempting to print gives this error (from /var/log/cup/error_log):
This means you don't have the necessary filters installed to convert the files. The problem was that esp-ghostscript and ghostscript were separate ebuilds. Since cups require the esp-ghostscripts filters, it could not use these unless you had it installed.
Unable to convert file 0 to printable format for job 3!
Updating ghostscripts (it is now under one ebuild), should fix this issue.
