I have not done this, but if you're desperate, sometime try distilled water
with just a _little_ household ammonia.

An alkaline solution (with the ammonia) is a great solvent for dried India
ink.  It just might work here, too, even though the printer ink is
definitely not India ink.  In desperation, it wouldn't hurt to try.  :-)
