TypeError: exceptions must derive from BaseException

[d-rez]

Hi there, thanks for making this! I was hoping to use this project for some thermal printing, I was able to print a couple test prints (image and text), however then it kinda just... broke?

I'm no longer able to print anything anymore, every time I try to (image or text), it connects to the printer but all I get is an Exception:

Exception occurred during processing of request from ('127.0.0.1', 55465)

Thanks in advance for taking a look
