Replace media error

[5shekel]

hi,
i introduced a new QL-1050 (spec) printer to my collection.
and i get this

$ brother_ql -b pyusb --model QL-1050 -p usb://0x04f9:0x2020 print -l 102 /temp/aaa.png
WARNING:brother_ql.conversion:Need to resize the image...
INFO:brother_ql.backends.helpers:Sending instructions to the printer. Total: 128286 bytes.
ERROR:brother_ql.reader:Error: Replace media error
ERROR:brother_ql.backends.helpers:Errors occured: ['Replace media error']
WARNING:brother_ql.backends.helpers:'printing completed' status not received.
WARNING:brother_ql.backends.helpers:'waiting to receive' status not received.
WARNING:brother_ql.backends.helpers:Printing potentially not successful?

i installed the p-touch software and noticed the printer communicated back to the software that the printer detected a 4"x6" label. its not right as mine is 4" (continues).

my questions,

• can/is there a way to disregard that automated label detection?
• mechanical\electronically, how this detection is done?
• can this be connected to the error im getting?

Answers to your questions:

1. The print job contains the media type info, the printer simply checks if the incoming data matches the currently loaded media, and report an error if it's not a match. So you can specify whatever you want with brother_ql just like you can with P-Touch, but the printer will still reject it if it's incorrect.
2. Detection is done with the holes at the bottom of the roll holder, you can find some microswitches in the area this section lands at.
3. Yes, if P-Touch detects a 4"x6" media then brother_ql isn't doing anything wrong, the printer thinks it has a 4"x6" media roll loaded and rejected the job meant for a 4" continuous media roll. If you have those aftermarket rolls with reusable holders/frames, make sure you are using the correct one and not just reusing them based on width.
