System-Level Command Functions

STX c Set Continuous Paper Length
This command sets the label size for applications using continuous media. It disables the top-of-form
function performed by the Media Sensor. The sensor, however, continues to monitor paper-out
conditions. See <STX>M.
Syntax: <STX>cnnnn
Where:
nnnn
- Specifies the length of the media feed for each label format, in
inches/100 or millimeters/10 (see <STX>m).
Sample: <STX>c0100
This sample sets a label length of 100, which equals 1.00 inch (assuming Imperial Mode is selected).
 Note: This command must be reset to zero for edge or reflective sensing operation.
STX d
Set Double Buffer Mode
(Non-Display Models only)
This command, available for backward compatibility, enables double buffer mode. When printing
labels with incrementing, decrementing and replacement fields (see note below) the printer will only
erase and format those fields, leaving the rest of the label format untouched, and thus increasing
throughput. This command is only active if the labels being printed are less than half the maximum
size of the print buffer (see <STX>S).
Syntax: <STX>d
 Notes: (1) This command is generally not used because fast formatting is the normal operating mode when
the number of variable print fields (Label Formatting commands +, -, <, >, u) is less than or equal to
1/3 of the print field count total. In this case, the command will force fast formatting even when the
proportion of variable print fields is greater than 1/3 the total.
(2) The maximum label size is unaffected by this command.
(3) The <STX>s command restores normal (fast) formatting.
