I successfully changed codepages with hex codes but I have issues printing qr images and barcodes. Instead of qr it prints following.

I follow this documentation https://www.dieboldnixdorf.com/-/media/diebold/ag-downloads/poslotterysystems/manuals/peripherals/thxxx/th250_programmers_guide_english.pdf

To fix printing qrcode in this printer you need to use image-mode. Load it as image via qr-image. Guess some sequences are not right for qr printing.
