The cabins of commercial planes are pressurized, meaning the maintain a
constant pressure without reference to the actual pressure outside the
plane. All commercial planes are pressurized to the equivalent of 8,000
feet, regardless of the altitude the are flying at (above 8,000 feet, of
course). Commercial planes can fly as high as 40,000 feet and, rarely,
above. However, the cabin is still pressurized to the equivalent of 8,000
feet.
The difference between 8,000 feet and sea level shouldn't be enough to cause
the ink blow as the OP described.

No, it wouldn't. No one can breathe at 30,000 feet, and most people require
oxygen above 15,000 or so.

No, the baggage hold is pressurized as well. Moreover, no one should ever
pack valuables, including printers, in checked bags -- it's an invitation to
damage and theft.

Well, unfortunately the way you see it is based on an incorrect
understanding about commercial airliners, specifically, regardless of
altitude, all commercial planes are pressurized to the equivalent of 8,000
feet and baggage holds _are_ pressurized.
