5. APPENDIX5.1 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 printable size of a bitmap image is 576 dots for STANDARD MODE. In PAGE MODE, the
maximum printable size of a bitmap image is 831 dots in the “y” direction (paper feed direction). (However 831
dots are reserved for “y” of the print area set by ESC W and the value of print direction “n” specified by ESC T is
1 or 3.)
