Apollo Transparency Film for Inkjet Printers - Compatible with HP, 50 Sheets/Pack (VCG7031S) - Perfect for Presentations, Overhead Projectors, and DIY Crafts

I've used a couple of these in an older HP DeskJet printer and they work perfectly. The ink dried quickly and doesn't smear. The package recommends these ONLY for HP printers. I haven't tried them in any other printers but the company has other products for those. (I use transparencies to grade test papers quickly by printing the answer key on a transparency and cutting out little slits with a razor blade so I can put marks on the test paper underneath.)IMPORTANT: Remember to position the sheet in the feeder so the ink is applied to the rougher, matte side, not the glossy side. Unfortunately there was nothing about this on the package but I knew to do that from using similar products in the past. Also remember to change the paper type in the printer settings.
