Der Drucker wird nicht erkannt.

When I first learned about that feature, I tried it just to see how it worked. I have a large business HP laser printer (LaserJet M550) and it would never even power on the Trezor. Then I tried a cheap lexmark inkjet printer (which I no longer have), and it worked. I didn’t really have a good use for printing transactions, so I didn’t use it that way other than just playing with it. So you might try a cheap printer like that and see if it works.

Are you plugging the Trezor INTO the printer??? That’s not right. You need a computer, and even then, I’m not sure how you would automatically print anything.

You might need a printer that’s designed to read photos off a USB – the Trezor will send it an „image“ to print. Just a guess though

Why are you using the Trezor for this at all? New transactions are public info, this information could be scraped or printed from any block explorer. Seems risky to expose your private keys like this, is the benefit worth that risk?

I’m not sure what you’re expecting to see. To print recent transactions, your Trezor would need to be unlocked and able to read from a node, to understand the state of the blockchain, before printing transaction info. It doesn’t have a modem, let alone memory for a network stack. How would a USB printer know what to do with it?

First, could you please link where you read that printers are supported.

Second, it sounds like printing out your emails, thats not good idea imo.
