TerraSlate Copy Paper Waterproof Laser Printer, Rain Weatherproof, 5 MIL, 8.5x11-inch, 50 Sheets

Bueno con impresoras láser

I purchased this to make outdoor signs on a laser printer and was not disappointed, it functions much like paper but is weather resistant. Mileage may vary depending on how your printer's toner can take the sunshine. One caveat, don't choose "overhead transparency", at least with HP LaserJets, the toner doesn't transfer completely to the "paper" and creates repeat ghost images. I found I had best results choosing "HP Cover Matte 200g" as the paper type, looks just like printing on actual paper (other paper type settings might also work but the price per sheet discouraged experimentation).

I used this to print out checklists and quick reference info for sailing in the Pacific Northwest, where it rains almost every day. I used a Xerox color laser printer and printed on both sides of each sheet. Every sheet came out perfectly. No jams, no melting, no curling, no running, no smearing. Vivid colors, clear text, even with small font sizes (6 point). As a test, I dunked one of them in water and held it there for tens of seconds, then pulled it out and tried to smudge the toner and tear the paper. The water just dripped off. No toner smudges whatsoever. Where I tried to tear the paper, it just sort of "dented" slightly. The one-star reviews (and some of the 3-star reviews) are from people who tried to use an inkjet, which the instructions clearly state is not supported. One person complained that the paper is not useful for painting ink on, which is clearly not the intended use case for this paper; it's meant for making waterproof durable laser printouts (or xerographic copies -- which I haven't tried). It's literally in the name of the product: "...Waterproof laser printer..." I wish Amazon provided a downvote button to indicate that those reviews are useless for assessing the utility of this product. Those reviews do serve to inform buyers to follow instructions though. Discovering this stuff makes me want to concoct more reasons to print waterproof documents. I'm curious to know how this compares with either Rite in the Rain paper (which is less expensive).

Amazing paper but not A4

Very good quality product , they sustain laser printing pretty well and we used prints on a few dives.. impossible to tear
