5. APPENDIX
5.1 Explanation on PAGE MODE
5.1.1 Overview
The printer has two print modes: STANDARD and PAGE.
In STANDARD MODE, the printer prints or feeds paper each time it receives a print or paper feed command. In PAGE MODE,
when the printer receives print commands and/or form feed commands, it simply forwards them to the specified print area of
memory. Only when an ESC FF or FF is executed all the data mapped in the print area will then be printed in a batch.
For example, suppose you executed a print and line feed for data “ABCDEF”<LF>. In STANDARD MODE, the data “ABCDEF”
is printed and paper is advanced one line. In PAGE MODE, the data “ABCDEF” is written in the specified print area of memory,
and the memory location for the storage of the next print data is shifted one line.
The printer enters PAGE MODE with an ESC L, so that all commands received after that point are handled in PAGE MODE.
When an ESC FF is executed, the data received until then is printed in a batch. When an FF is executed, the data received until
then is printed in a batch, after which the printer returns to STANDARD MODE. An ESC S causes the printer to immediately
return to STANDARD MODE; any print data, however, that has been stored in PAGE MODE is not printed. Instead it will be
cleared.

5.1.2 Values Set by Each Command in STANDARD MODE and PAGE MODE
(1) The values set with commands are common to the STANDARD MODE and PAGE MODE. The values set with any of
the commands listed below are, however, treated differently and stored separately for the STANDARD and PAGE
MODES.
• ESC SP, ESC 2, ESC 3, FS S
(2) The maximum number of print dots in the horizontal direction is the print area width (usually 576 dots / 3 inches) in the
standard mode. However, when using the y direction (paper feeding direction) in the page mode, printing exceeding the
printing area width becomes possible.
However, when the printing area width in the y direction is secured by <ESC W> and the value in the printing direction n in
<ESC T> is 1 or 3.
