Thermal Printer - Status

Other Miscellaneous
1

I (the Arduino) want to know, that the printer is connected.

Currently my program is doing that:

Arduino starts

Printer offline(), → the led of the printer is off - I can see that the printer is connected

NOW I want the show on a display

Printer connected: yes/no

The Printer has to communicate with the Arduino.

How can I do that?

Hello, and thanks for your post!

If you have a look at the data sheet, there’s a command on page 10 that returns the current status of the printer.

With that command you can tell if the printer is connected, if it has paper, if there is a power issue or if the printhead is overheating. The data sheet can be found at the link below.
