P1003636-002 TTP 7030™ Technical Manual 10/05/2009
Moves the print-position one step to the left. Backspace can be used to combine characters.
For instance to print a Ø, send text commands O BS / to the printer, and the slash will
overprint the O.
Only one backspace can be used at a time. Excessive backspaces will be ignored.
Cancels text and attributes sent before the <CAN> command on the same line.
Commands, are not cancelled.
By default, carriage return is ignored.
By changing the default settings, you can:
1. Interpret is as <CR> which returns print position to beginning of line without line feed.
2. Interpret <CR> as <CR><LF> which inserts line space as specified by the line spacing
setting (see parameter p13), and returns the print position to beginning of the line.
See “Carriage return and line feed behavior” under CR/LF Behavior on page 78.
Linefeed is interpreted as <CR><LF> by default. This inserts line spaces as specified by the
line spacing setting (see parameter p13), and returns the print position to beginning of the line.
<LF> also converts text from the input buffer to pixel lines and stores them in the line buffer,
ready to be printed.
By changing the default settings, you can:
1. Interpret <LF> as Linefeed. This inserts line space as specified by the line spacing setting
(see parameter 13 on page 77), without returning the print position to the beginning of the
line.
2. Ignore <LF>.
