04 Align Column Right
Default:
n = 00
Remarks:
v Values 00, 01, and 02 are only valid at the beginning of a line.
v Tabs are only valid when printing is aligned to the left. If tabs are used
when left alignment is not used, results can be unpredictable. (See “Tab
to Next Tab Stop” on page 152.)
v Alignment is relative to the left margin.
v To use the Align Column Right command:
1. Send the characters that you want to be left aligned.
2. Send the Align Column Right command.
3. Send the characters that you want to be right aligned.
4. Send an end of line command, for example X'0A' or X'0D'.
The printer will return to left aligned after the line is printed.
Limitations for n=04:
v The command is only valid in the cash receipt station.
v The command is ignored if the printer is not left aligned when the
command is received.
v If the Align Column Right command is received but the line is filled
before an EOL is received, the filled line is treated as an EOL. There are
usually a few dot positions available, but not enough for a full character.
The column alignment will occur on the few dot positions available.
Set or Cancel Unidirectional Printing
RS-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 printhead 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 printhead.
In bidirectional mode, printing double-high characters takes only two passes
of the printhead.
Unidirectional printing takes longer but increases the quality of the print.
Set Error Recovery Function
RS-232 Syntax:
ESC c 4 n or X'1B63;34;n'
