What brand laminator is being used in this discussion? Did your printer come with software to get 1200 times 1200 dpi or did that matter to get your results?

I’ll give it a try with a 2” lens as that’s then most common size in these hobby lasers. I do have a 1.5” one (somewhere) and might order a 1” if

Does your HP 1102 have HP-brand toner, or aftermarket? Sometimes this makes all the difference (either way). Regards, --Kirk, NT0Z Rochester, MN My book,

That’s encouraging, I should get around to trying it. The CO2 lasers most people own (the ‘eBay lasers’) have a spot size of 0.1mm – 0.3mm depending

The alcohol is there to dilute the acetone so it does not dissolve the toner completely. Correct. The alcohol acts as an inhibitor to the agressive nature
