This reverts commit e338d6a0fc. I originally
reverted the update because it broke my Samsung printer. Now, it turns out that
this issue can be fixed by deleting and then re-creating the printer in CUPS to
update the driver.
It's possible that Gutenprints 'cups-genppdupdates' could remedy the situation
as well, but I had no chance to verify that since I don't use Gutenprint.
