Review on ColorPrint Compatible Toner Cartridge Replacement - High-Yield 94X CF294X/CF294A for M118DW/M148DW/M149FDW Printer (Black, 2-Pack) by Mitch Warner

I bought this when the light came on for my HP laser printer. As soon as the original cartridge was empty and started showing lines, he went in for a replacement. Now that the return period has passed, I have found that when installing these aftermarket cartridges, the printer says "THE TONER MEMORY SEEMS TO BE MISSING", rendering the cartridges essentially unusable. DO NOT BUY!
