Brother QL-800

[Carlos Rodriguez]

Hello everybody, 

I am currently setting various  Brother QL-800 to print some qr codes from some hosting.  

My current issue is that the printer does not respond to any command from the demo.  I can currently print from the ptouch software, and a pdf viewer, but nothing from either the demo or the code implementation. Here are some logs if needed.

The QL series from Brother works with QZ-Tray, but there a few things to note:

The command language for the printer is ESC/P, which is different from ESC/POS, and you may have to change the printer's settings to use this language.

https://qz.io/wiki/raw#escp

If you're printing a PDF or another pixel job, it should just be a matter of having the printer in the correct mode and choosing the right dimensions for the label size.

Here's a recent thread where another user and I adjusted the printing configs are were both able to successfully print a PDF to a QL printer.

I have a QL-820NWB for testing, so if you run into issues, I can test them on my hardware and offer suggestions to get things working correctly.

Thanks, I'll check it out. I missed the part that esc/p and esc/pos were different and I'll check out more carefully the thread you mentioned.

Many thanks.

Carlos:

Please accept my apologies. I was mistaken about the QL-800 being able to interpret ESC/P commands. I realize now that the QL-810 and QL-820 can process them, but not the QL-800. You will want to use raster graphics instead with this model.

I have managed to print from pixel, but it wasn't the solution. When I tried to use the esc/p example from the wiki, it didn't print at all. I'm attaching the logs of the failed esc/p

Thanks Lite for the help, but I have managed to print through pixel our solution.

Thank you so much for the support on qz-tray.
