I've never written a kernel driver, but wouldn't it be easier to start with the 32-bit driver, update the kernel APIs, and move (most?) integer types to fixed-width?

It looks like the 32-bit driver is closed source. The download doesn't contain any source code, despite the text on this page. https://www.canon-europe.com/support/consumer_products/products/printers/inkjet/pixma_ip_series/pixma_ip1800.html?type=download&language=en&os=linux%20(32-bit) https://www.canon-europe.com/support/consumer_products/produ...

  The source is available in several GitHub repos including at least one which claims to have updated the code to compile on modern systems.

That's exactly it (not sure if the kernel USB API is the same, that might be a tricky part)

Printer drivers are user space.
