6.5.4 Tear-off and type of data
When the tear-off is valid, the printer monitors the print data for 0.5 second
during or after printing. If print data is transm itted within 0.5 second during or
after printing, the printer will start next printing without tear-off. (When data is
received during printing, the time of monitoring 0.5 second is not inserted.)
The commands for this printer are mainly classified into the immediately
execution commands starting with "SOH" and the sequentially execution
commands starting with "STX." In the tear-off function, only the
sequentially execution commands related to print processing contents are
monitored but the immediately execution commands are not monitored.
Therefore, even if the printer status or the remaining number of print sheets
is read out by using the immediately execution commands during printing,
the tear-off will be performed after printing. On the other hand, if the
sequentially execution commands are used during printing or within 0.5
second after printing to transmit print-related data, the printer will start next
printing without tear-off. (For details, see the Command Reference.)
6.5.5 Cut position adjustments
• The cut position can be set with the "fnnn" of the system-level
commands. When the tear-off function is turned on, the following
initialization value is set in the printer.
Initialization value: fnnn = f733 (73.3 mm)
The values higher or lower will increase or decrease the amount of feed
in the tear-off.
Onnnn: Paper position setting
fnnn: Feed position setting
fnnn <= Onnnn
