Hi all,

I'm using Star-Dust's SD_BT_Printer (which is great, by the way).

Does anyone knows if there's any way to detect printer errors with it? I'm mainly looking for the "out-of-paper" one.

Thanks.

SD_BT_Printer / ESC_POS

It will depend on whether your printer has these paper sensor functions.


Select paper sensor(s) to output paper-end signals​

How @oparra spelled correctly depends on the printer. Some printers use the DLE EOT n command (see here)
The response comes in the DataReceived event.

Please note that some inexpensive printers do not provide the possibility of Bidirectional communication, but it is only possible to send data through bluetooth

You're right.

It was just a reference to the ESC / POS commands, and it will depend on the use of these commands according to the specifications of the printer.

ESC / POS = EPSON and the printers that emulate these commands.

ZPL = ZEBRA

etc.

Cheers,

Note:
TM-T20 (EPSON)


GooJPRT PT-210 (emulate command ESC/POS)

We have the programming manuals, we import some of the factory from China
