I don't know how big a problem having the keyboard locked
during printing would actually be. My part-time job is in a
hardware store that uses a POS system similar to the one
you are describing. All of our registers are 386's networked to
a backroom server. Each register has its own dot matrix printer,
but while it is actualy printing the keyboard is locked.
This has never been any problem. While the keyboard is locked we are
waiting for the invoice to print and/or the cash draw is open and we
are making change. I should note that the invoice only prints
after the sale is finalized.
Actually the very first version of this POS system used WYSE
terminal and there pass through printing feature.
