How to decode this error when using Raspberry Pi to send an image to a QL-800 printer in Python?

I print Picture X. I then try to print Picture Y but it prints Picture X again followed by Y. Please, how can I delete Picture X from a Python list?

Everything installed fine to get the Raspberry Pi version of the brother printer driver. I used https://support.brother.com/g/b/downloadtop.aspx?c=us&lang=en&prod=lpql800eus and I used https://pypi.org/project/brother-ql/

Using the traceback, how can I understand what value I should use for the variable "printer"? I think that is the issue.

Here is the code:

(moving comment to answer)

In your code, you are specifying the printer path as /dev/usb/lp0 but specifying the backend as pyusb. For USB, the library expects a path like 'usb://0x04f9:0x209b' which caused the error you see. The path you have (/dev/usb/lp0) indicates a linux_kernel backend. Try updating your code accordingly.

This code is for printing badges for COVID-19 screening on a brother QL-800 printer.

I am using the amazing code someone created found here https://github.com/pklaus/brother_ql/tree/142cf744d89a912df729bbf15d35468d780559df/brother_ql

Apparently, each time I call the convert() or send() functions, the python code maintains the badge I am printing in a list.

So each time I try to print a new badge, it first prints all the old badges.

Can anyone see how to remove the badge image from the list after I do the convert() and send() commands to print?

HERE IS THE CODE:

Reading the documentation here shows that convert adds a rasterised instruction for the current image to the data sent to the printer. Likely, you need to reset the data to be sent before the second send()

One way would be to use qlr = BrotherQLRaster(model) before the second convert() but I can't test this to know for sure since I don't have a Brother printer.
