How do I found out what toner cartridge each of the laserjet printers uses?
comparing the lj pro 401 dne to the lj pro 1606dn
I typically search the make and model of the printer with the word toner after it in the search bar and it always comes up ( ex. HP 3015 toner). If you already have a toner cartridge in your printer you can just read the toner number and or model number on the cartridge itself. Then just search for that. I hope this helps.
