Review on 🖨️ APOLLO Transparency Film: Black on Clear, 50 Sheets/Pack for Laser Printers - CG7060 by Sam Lee

I bought them for PCB fabrication with my HP LaserJet 2300dn. Before printing anything, I put in a brand new toner cartridge and tested it with plain paper, which printed fine on it. Before wasting copper circuit boards, I decided to test print image and text on these foils. Both didn't work at all. In the text, the toner is scattered around most of the letters, regardless of the toner density I use. The image had an odd spot, as if the toner hadn't dried before hitting the rollers inside the printer. I'm glad I tested beforehand. I wouldn't buy them again for any purpose.
