I was quite surprised of the printing quality as well.

Never had it clog up. But I have all kinds of issues with that printer. Always connects to the network but randomly refuses to print. Sometimes it only prints half a page. Sometimes it prints half a page and retries by itself. Scanning is pretty much impossible on macOS because the drivers aren't maintained. etc...

It's horrible. But when it prints, the quality is good...

Honestly, I get cold sweats from the thought of having to print something.
