Do you have examples for models of laser printers can actually achieve a resolution of 10000dpi? It doesn't need to be office equipment. Any example would suffice as I so far thought that laser printouts were limited to a maximum resolution between 1200 and 2400dpi.

Not at home, but at professional printing houses absolutely.

This isn't hypothetical, I've done it -- in grad school we would send out (I believe) 30000 dpi print jobs on transparent polyester film, and then adhere those to glass blanks to create cheap masks for MEMS fabrication. We had an old Canon i-line lithographic aligner that accepted the glass blanks.

I think the print jobs cost us about $100 each.

Here's the first Google result for a vendor (I don't remember who we used). There's a price list on their page and it looks like they have capability up to 50,800 dpi.

If you're willing to go 10um then it's even easier and one can use a DLP to go maskless.
