3.1. Print action codes
(1) CR (Carriage Return)
When the CR code is transmitted to the print buffer, all data stored in the
print buffer is printed. When AUTO FEED XT (Pin No. 14 of the interface
connector) is at “LOW” level, the paper is advanced one line automatically
after the execution of printing by the CR code.
NOTES: 1. When 80 columns of print data (including spaces) are continuously received
and the following data is valid and printable, the Printer automatically
begins to print the data stored in the print buffer. (In this case, if AUTO
FEED XT is at “LOW’ level, the paper is advanced one line after printing.)
2. If no data precedes the CR code, or if all preceding data is “SPACE,” the
carriage assembly does not operate. Under this condition, if AUTO FEED XT
is at “LOW” level, only paper feeding is performed.
3. When all 80 columns of data are “SPACE,” the carriage assembly does not
operate. Under this condition, if AUTO FEED XT is at “LOW’ level, or if
the DIP switch pin 2-3 on the control circuit board is ON, only paper
feeding is performed.
(2) LF (Line Feed)
When the LF code is input, all data in the print buffer is printed and the
paper is advanced one line.
NOTE: If no data precedes the LF code, or if all preceding data is “SPACE”, only paper
feeding is performed. For example, if the data is transferred in the order of
DATA -> CR -> LF, DATA will be printed by the CR code, and when the Printer
receives the LF code, it only carries out one line feed, because no print data
precedes the LF code.
(3) VT (Vertical Tabulation)
When the VT code is input, all data preceding this code is printed and the
vertical tabulation is made to a predetermined line position set by “ESC B”
(up to 8 positions). If no vertical tab position is set by ESC B, the VT code
behaves like the LF code. Therefore, the paper is advanced one line after
printing.
(4) FF (Form Feed)
The FF code causes the Printer to execute the printing of all data stored in the
print buffer and advances the paper to the next predetermined Top of Form
position.
