There is no sign of a printer board in the dmesg output.
Could be a defect board but (at least to my experience) this is often rather due to:
- Messed up Linux systems, e.g. your seem pretty old and the old sunXX driver and the distributions based upon them are not exactly stability monsters. If you feel comfortable installing Linux, you could probably try an original Armbian server version
- Other typical issues are listed in Issues flashing the printer board
