I think the idea is that "laser" should have filtered out the results he was seeing, but it didn't. Furthermore the content on the pages is explicitly lying about the fact that they are laser printers and drowning out the pages that aren't lying. It could just be that Pagerank doesn't work for this type of information organization anymore. It may not be a Google problem but an internet search and Pagerank problem, especially if Bing and Duck Duck Go aren't any better in this regard.

People add Reddit to their searches specifically to add some social context to this information retrieval, rather than purely spam-filled Pagerank-based information retrieval.
