Tear Bar Distance
This option allows fine and course adjustment of the tear bar position. For a
printer with a quick access cover using the front paper exit, the default (5.12
inches) is used. You can specify 4.5 to 10.5 inches in .01 inch increments to
accommodate variations in cover and form design. If the printer is not equipped
with a quick access cover, or when rear paper exit is desired, the tear distance
should be set to accommodate the rear position. This requires setting the Tear
Bar Distance to 9.92 inches.
Shuttle Timeout
This refers to the amount of time the shuttle continues moving after no data is
received. If your host is slow, setting the number to a higher value will prevent the
printer from spending time shuttling up and down between data bursts.
