Android Question SD_BT_Printer - any way to detect out of paper?

[mmanso]

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.

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

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,
