I had something similar happen to me, but not the part about printing.
Just about GRUB not booting.  Happened twice in the past 2 months, with
FC6.

Things seemed to point to faulty hardware to the point of me buying a
new hard drive, but I ran a bunch of diagnostic checks on my hard drives
and they all pass.

GRUB is on my MBR, so to reinstall it I booted off the rescue CD, did a
chroot /mnt/sysimage, and then

grub-install /dev/sda

Your install procedure will be slightly different.  My guess is

grub-install /dev/sda1

or something like that, but you'd better check carefully because I don't
know all that much about GRUB.
