reset_resume() is supposed to restore all state. The printer driver does
not know which state a printer is in, except for the trivial case of the
printer not being in use, as it doesn't know the meaning of the data
going to the printer.

You might argue that you deserve what you get when you hibernate
while printing, but then it makes no sense to implement it anyhow,
disconnection and reconnection work just as well and are cleaner.
The same is true for many devices.
