Review on Smart Ink Compatible Cartridge Replacement Computer Accessories & Peripherals in Printer Ink & Toner by Jesse Hughes

Thought I'd try this ink instead of buying HP inks and it worked for 2 pages which were printed on different days, but when I wanted to type something this week. Nothing. blank pages came out. I've run a print report etc, cleaned the printhead etc, but still no black ink. It prints the colors in squares in the print report/tests, but nothing comes out when I print the document. Sent a message, we'll see what they say. This was for the HP 6500A printer
