Yes I agree, I think that serialized input+print that would require use of
the keyboard while the previous print is still being done is rather unlike
to be the job of a POS terminal... such heavy data entry could require
less frequent print operation, or could probably be designed for not
printing after each keyboard entry, or, last, could send the prints to a
printer connected directly to one of the LPTs on the Linux box.

Why did you move to networked 386's? What's running on them?
