12.APPENDIX 1. PAGE MODE
12.1.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.

[Switching Between STANDARD MODE and PAGE MODE]
Command values in STANDARD MODE and PAGE MODE:
(1)The values set with commands are common to the standard and PAGE MODES. The values set with any of the four commands listed below are, however, treated differently and stored separately for the standard and PAGE MODES.
• ESC SP, ESC 2, ESC 3
(2)The maximum printable size of a bitmap image is 576 dots for STANDARD MODE. In PAGE MODE, the size can be extended up to 575 bits in the y direction (Paper feed direction) if 575 bits 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.
