Review on 🖨️ Cool Toner - Compatible Toner Cartridge Replacement for HP 78A CE278A - Laserjet 1536dnf MFP, P1606dn, M1536dnf, P1566, P1560 - Printer Ink (Black, 4-Pack) by Awiwi Swift

Does not fit my HP LaserJet P1606. Prints a page and then throws an Attention Required error. Does not say what kind of attention is required. The only way to get the printer working again is to unplug the printer and reinsert the HP OEM cartridge. Also still says printer ink runs out on first print. UPDATE: We ordered these for our store. As this is a shop we ordered them as soon as we installed our latest HP OEM cartridge this past April. We only installed them in our printer at the end of July (well after the return period had expired). I contacted Toner H Party to ask for a refund even though we missed the deadline and they immediately refunded the purchase price. Very good customer service! 1 star for the cartridges as they didn't work, 5 stars for the company's customer service!
