Review on Get Quality Prints with HP 78A/CE278D Toner-Cartridges for LaserJet Pro M1536 and MFP P1606 by Tom Roberts

I have had an HP1606dn copier for a few years. At first I bought generic branded cartridges but then switched to HP 78A toner cartridges. Compared to original HP 78A cartridges, normal branded cartridges seemed to run out much faster. I suspect generic cartridge manufacturers refill them with less toner powder. Generic manufacturers are worth their money in my opinion. The lower price leads to less good specimens.
