Appendix 1. Page Mode - Citizen iDP-3221 User Manual

APPENDIX 1. PAGE MODE

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, will all data mapped in the print area until
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 shall be deleted.
