TI Model 855 Printer DP Emulation 6-10
The next character printed following a BS command over-strikes the
most recently printed character. In the backward print mode, each BS
control character moves the printhead to the right one space.
The BS command can cause characters to be printed to the left of the
left margin in the forward print mode or to the right of the right
margin in the backward print mode.
Tab Horizontally
Control character: HT
Hexadecimal:
09
This command advances the printhead to the next horizontal tab stop
and the printer starts the next print operation at that position. If the
printer receives an HT command following the last horizontal tab
stop on a line, the printer performs a carriage return and a line feed
and starts the next print operation at the left margin.
Carriage Return
Control character: CR
Hexadecimal:
0D
This command causes the printer to perform the following functions.
q The printer prints the current line of data from the print buffer
and begins the next line at the left edge (column 1), set via the
form configuration menu.
q If right margin justification is active, the CR command causes
each line of print to occupy the entire space between the left and
right margins
q If the expanded print mode is active, the CR command resets the
printer to the normal print mode.
q If the automatic line feed function is active, the CR command
causes the paper to advance one print line.
