I didn't go totally crazy, though, and stopped before getting too deep into "...and then OCR them using the check scanner" because I remembered I was already keeping track of start/stop times in a database when printing the slips.
Fun fact... the original implementation was in OpenQM, that is, a PICK-style system.
I place them on a ticket rack hanging on the wall above my monitor. It like the ones you see at restaurants... extruded aluminum... filled with marbles... slot on the bottom. If my board is full, I can't (or at least shouldn't) accept more work. It also is an immediate reminder of what needs to be done. The physical process of marking a ticket done and putting it in the finished pile helps to satisfy that need to have a visible sign that work has been done.
(Thank you)
One thing I solved differently: I rendered the fax as an image using PIL and then I just print the image. That way I can support arbitrary Unicode and can lay things out independently of what my printer is capable of.

They are used in kitchens, as heat sensitive paper doesn't work well there. It's just plain paper and an ink ribbon.
Same underlying protocol as thermal printers, so the code is mostly plug and play.
They often can print in two colours (red and black). And sound like the 1980s.

The first was a todo list printer where the todos are written in a YAML file. It includes fields for the name of the list and the date.
I also started working on a Sudoku printer (which I think is only possible on 80mm paper). But I completely forgot about the entire thing after coming back from vacation.
You've inspired be to get back to working on it :D
As an aside, are there any good recommendations for a wifi/bluetooth printer using 80mm paper that doesn't break the bank? I initially bought the Munbyn ITPP098P but it being USB only is a bit unergonomic.
I wanted to setup https://www.colonnes.com but their recommendations were quite expensive.
It was configured with a fixed IP/subnet/gateway and no DHCP, which took an hour or two to debug and reconfigure. Been a dream since then: prints really fast and cuts properly. OP's project works well to print todo's.

I just bought one a couple weeks ago actually.
