Anyone using a Wincor Nixdorf TH230 (Image printing)

[Rdlgrmpf]

Hello everyone.

I am using this library with a Wincor Nixdorf TH230 that I got from eBay.
So far it works great and I can print images using the bitImageColumn implementation. According to the official programmers guide, graphics GS(L should also be supported. It prints only gibberish though.

The only weird thing is, that the table in the first screenshot does not mention function 112 (store in print buffer) but the Text underneath does.

Is anyone else using this printer and has the same problem?

Cheers
