Figured it out myself. Ditherting is not implemented with Red and Black printing.
Thanks for reporting this. Actually, it would be great if this works. I'll see, what I can do here. Do dithering before or after deciding/thresholding between black/red pixels? I have to try and see. For now, I'll reopen the issue.
I worked on the "conversion.py" that is posted on my GitHub page. Dithering is working but i cant get the contrast right.
My Setup
My Problem
i would like to print Pictures and Graphics with my QL-800. Unfortunately the printer produces only B&W Patterns and no gray- redscale printouts. Dithering has no effect. Could be related to Issue https://github.com/pklaus/brother_ql/issues/62
Any help would be much appreciated
Console
Printing command:
$ sudo brother_ql -m QL-800 -p usb://0x04f9:0x209b print -l 62red --red TestRG.png
Printing command with dithering
$ sudo brother_ql -m QL-800 -p usb://0x04f9:0x209b print -l 62red -d --red TestRG.png
