Flashing LED on QL-500 #1

Closed splitbrain closed 7 years ago

splitbrain commented 7 years ago

I'm trying to use this interface to create a label on my Brother QL-500 but all that happens is that the green LED is flashing.

Here's what happens when I use the label designer:

The server was started with:

./brother_ql_web.py --model QL-500 --loglevel DEBUG file:///dev/lp/printers/usb-Brother_QL-500_F4Z731433

Anything I can do to help debugging this?

Hi @splitbrain and thanks for reporting the issue.

If you start brother_ql_web.py with --loglevel DEBUG, it will not print but save the label to a file instead: sample-out.png. I should make that more clear in the README / CLI --help.

If you were trying without the DEBUG mode before, it should have worked. If it doesn't, please make sure, you are using the right labels. Currently brother_ql_web only works with 62mm continuous labels. So put in the right labels and ideally power off an on again your printer. Secondly, check that you are using an up-to-date version of brother_ql (pip install --upgrade brother_ql).

Yeah I tried without DEBUG before with the same result. However I'm using 62x29 labels.

pklaus commented 7 years ago

That's the problem. I didn't spend enough development effort so far on it to make it work with different label sizes. I want to add this some day though.

pklaus commented 7 years ago

I added initial support for different label types in commit c8b3c50. Please get the latest version and check again. Not all label sizes are in the list yet, but this will follow together with an option to center the text in die-cut labels.

Now die-cut labels will automatically have centered text (commit b59f981).
