I can’t say I’ve ever had many issues with Canon’s PRO line and I’m aware of a few pro photographers who use them, certainly putting them at the same level as an entry level inkjet or laser seems a bit disingenuous. Definitely more expensive than one-offs at a good print shop, but as I say it’s a hobby - finding time to get to a good print shop while they’re actually open can take weeks which is next to useless in some cases.
