Self-Printing; Hexadecimal Dump Printing - Citizen CT-S281 Mode D'emploi

4.5 Self-printing

Insert paper into the printer. With the FEED button pressed and held, turn the
printer power on, keep the FEED button held for about 1 second, and then
release the FEED button. The printer starts self-printing. The printer prints
model name, version, DIP switch setting, memory switch setting, and built-in
fonts.

4.6 Hexadecimal Dump Printing

This function is to print all received data in hexadecimal numbers. If problems
such as missing data, data duplication, etc. should occur, this function allows
checking whether or not the printer is receiving data correctly. Set paper to the
printer and keep the paper cover open.
With the FEED button pressed and held, turn the printer power on and then
close the paper cover.
The printer prints "HEX dump print mode" followed by the received data printed
in hexadecimal numbers and some characters.
CAUTION!
● The printer prints "." if there is no characters corresponding to data.
● During hexadecimal dump, functions except some command will be disabled.
● If print data does not cover a line, press the FEED button to print the line.
When you press the FEED button three times consecutively, or you turn the
printer power off, or the printer receives a reset signal from the interface, the
hexadecimal dump printing is terminated.
