Don't perform printer font substitution

The so called printer resident fonts is a relic of a bygone era, when
life was simple and there was only ASCII and Type1 fonts.

It is just broken by design these days, offers nothing useful and can go
wrong in many ways. Since 1f3a91cf2ace315fb332c0149808a2433eb9ae71 this
"feature" is disabled by default anyway, so scrap this code to make room
for some long due cleanup.
