4. APPENDIX

4.1 Explanation on PAGE MODE

4.1.1 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.

4.1.2 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.)
