412 Operators Manual 44
^A ^D Command
39 Auto-Size Label:
0 Clears the use of auto-size values set by ^A1^D39.
1 Uses the values obtained for the variables above instead of what the user
supplies in the header of the file format. This will not display the variables on the
screen.
2 Automatically sizes the label and displays on the screen the values for the size
variables. These values should be placed in the label header for that stock.
3 Same as ^A2^D39, but prints the values on a label, instead of on the screen.
5 Diagnostic Mode
(Note: The LCB should be set to 1 before auto-sizing black line stock.
^A1^D47)
XX 91 Gap Detection Sensitivity: The proper value may be obtained using the
auto-size (^D39) command. The ^A value sets the point (0-255) at which
the printer detects a gap or black mark. When the printer is powered on
or reset, this command will default to 30 if using the transmissive sensor
and 120 if using the reflective sensor. Although the default value should
work properly with most media, it is a good idea to place this command
at the beginning of all format files in order to guarantee that it has not
been changed by another user or application. If this value is not correct,
the printer may not detect the end of the label and may feed extra media
or stop too soon.
