Templates

escpos-mqtt allows using formatting strings inside the message. If a setting (e.g. the font-size) is overriden inside a template, the default won't kick back in inside the same message.

Formatting can be prevented by adding a backslash before a formatting sequence.

A formatting sequence is build like this:

[CONTENT](COMMAND,...ARGUMENTS)

Valid commands are:

BOLD
REVERSE
FONTSIZE
BARCODE
QRCODE
CUT

CONTENT is optional and only supported for BARCODE and QRCODE types. BOLD andREVERSE are booleans and can be used like that. BARCODE has the following arguments:

type UPCA, UPCE, EAN13, EAN8
x-size 2-6
y-size default is 162

QRCODE has the following arguments:

model 1, 2
size 1-16
correction 48-51
