I tried the top several results (searching for "large-format laser printer" as per Adam Savage's rant). Most of the results contained no large-format laser printers and no useful advice on finding or choosing them. The most promising was an e-commerce page almost all of which was other things but one of whose items was indeed advertised as a "large-format laser printer". Unfortunately it was actually a "computer to plate" machine, suitable if you want to print very large numbers of identical copies of something, prices starting at a mere $20k, almost certainly in no way suitable for Adam Savage's needs.

(An earlier version of this comment listed the actual results and commented separately on each. Unfortunately, while trying to refresh one of the result pages which hung without displaying any actual content I accidentally refreshed the HN "Add Comment" page, which threw away everything I'd written, so what you get is the summary above. Sorry.)

Searching for "large format laser printer" also yields lots of inkjet printer SEO driven results on you site.

Specific examples? What country/language settings did you use?

I got (for UK/English settings)

Google: 5 Ads followed by https://smallbiztrends.com https://www.printerland.co.uk

DDG: 1 Ads followed by: https://plumbaroakland.com https://smallbiztrends.com

Mojeek: https://foodisforfuel.com https://www.cadtutor.net

Just looking at the domain it already looks like a massive failure in results. Clicking into the site it looks like a content farm. The top articles are:
