(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.
(3) VT (Vertical Tab)
When the VT code is input, all data preceding this code is printed. And the
paper is advanced to the line position set by "ESC B" (described later.) If no
vertical tab position is set by
Therefore, the paper is advanced one line after printing.
(4) FF (Form Feed)
The FF code carries out the printing of all data stored in the print buffer and
advances the paper to the next predetermined Top of Form position.
Top of Form is determined when the POWER switch is turned on or the l@j'i=i
signal is applied.
If the form length per page is not set by "ESC C+n," it is regarded as 66 or
72 lines.
NOTE: The form length of 72 lines per page is applicable to only the version
marked with identifier code "M72" on the rear side of the lower case of the
Printer.
This code always initializes the printing of the data stored in the print
buffer.
(5) SO (Shift Out)
When the SO code is input, all data that follows it in the same line will be
printed out in enlarged (double width) characters. This code is cancelled by
the printing operation or the input of "DC 4" code and can be input at any
column position on a line. Therefore, normal size and enlarged characters
can be mixed on the same line.
