Set or cancel unidirectional printing
EIA-232 Syntax:
ESC U n or X'1B55;n'
where:
n=00
Cancels unidirectional printing
n=01
Sets unidirectional printing
Default:
n = 00
Remarks:
This is valid in the document station in portrait mode only, when there must
be two passes of the print head to print one print line.
be two passes of the print head to print one print line.
Example: double-high or emphasized print.
When unidirectional mode is set to double-high characters, it takes three
passes of the print head.
passes of the print head.
In bidirectional mode, printing double-high characters takes only two passes
of the print head.
of the print head.
Unidirectional printing takes longer but increases the quality of the print.
Request document length for landscape print
EIA-232 Syntax:
GS N X'02' NULL or X'1D;4E;02;00'
Purpose
To determine the length of the document in the Landscape Print station
Remarks
v
Not supported on printer Models TI1 and TI2.
v
Document length data is sent in status bytes 9 and 10.
v
Status byte 5, bit 3, is sent to indicate that extra data (beyond status byte
8) is attached.
8) is attached.
Set document length for landscape print
EIA-232 syntax:
GS c 1 n where n = 2 bytes indicating the length of the document in print
motor steps.

Note: There are 50 motor steps per inch. A 6-inch document = 300 steps. (Use
295 to allow a margin for error; n=0x127.) To calculate the number of dots
per printed line:
per printed line:
