Printing speed using --lq is slower than AirPrint on Mac #86

Open johnlee999 opened 4 years ago

johnlee999 commented 4 years ago

I've been testing how to speed up on QL-820NWB. (MacOS 10.14) AirPrint is much faster than brother_ql with the option --lq. Actually, it seems to me that --lq doesn't change the speed nor the quality at all.

Is there a workaround to make the printing speed as fast as AirPrint?

FYI, I can't change both speed and quality when using AirPrint. It's always fast and low quality. CUPS driver allows me to fully control them, but it doesn't recognize a 62x100mm label...

Maybe I found the reason. --lq is actually supposed to be --hq. I'm new to both GitHub and python, so I'm sorry if this is misplaced. In my environment, however, changing the --lq to --hq solved the problem. (cli.py line:131 )
