ISSUE: What function does the front panel button perform?
SOLUTION:
The front panel button can be used to accomplish the following tasks:
-
Form Feed - If the data light and the Ready light are both on steadily,
there is unprinted data in the printer. This can happen with print
screens from DOS, or when using software that does not send an End of
Job or Form Feed command. Briefly press and release the front panel
button to print the data.
