Function Verifies data delivered to the printer was printed without any
mechanical errors such as a head jam or an out of paper
condition. n indicates the level of error reporting. The end of
the print job is indicated by the Esc e command. n is defined
as follows:
bit 0 =Determines auto report status at the end of the job
(when last line/form feed before ESC e is complete).
bit 1 = Determines status if paper was out during printing.
bit 2 = Determines status if there was a printhead jam during
printing.
bit 3 = Determines status when paper is loaded after a paper
out condition and the red button is pressed during printing.
bit 4 = Determines if printer times out during printing.
bit 5 = Determines if forward/reverse buttons were pressed
during printing.
bit 6 = Cancels timeout. Printer always stays on (timeout set
to 9999) but does not write to Flash.
bit 7 = Reserved.
Note 1: If all zeroes are specified for n, any active status
messages set by an ESC s n command without an ESC e
command are cancelled.
Note 2: Cancelled timeouts are not written to Flash;
therefore, the timeout returns to defaults if the printer is off
or if the power is disconnected.
Note 3: Timeouts can also be cancelled using the ESC t
command. ESC s 0 or ESC e will not reinstate a timeout
cancelled using the ESC t command.
