The difference is TN450 toner cartridges allow you to print over twice as many pages at standard page coverage compared to the TN420.
So both TN240 TN450 fit the same printers (models listed below) but the TN450 costs slightly more to purchase (especially if you buy genuine brother), however the increase in price is more than offset by the increase in printed pages especially is you use compatible toners.
These toner cartridges and laser printers they fit in are mono printers (black only). Compatible TN450 toners are the best value.
|Brother TN 420 standard yield toner– capacity is 1200 printed pages.
TN 450 high yield toner (compatible) – capacity is 2600 printed pages (better value).
The compatible TN-450 Toner I recommend is from House Of Inks if you live in the USA or Canada as they offer free shipping on orders over $40, totally reliable and quality compatible toners. Click here to save over 50% on TN-450 toner.

These toner cartridges do not feature any kind of chip (non chipped) and if you choose to save even more money by purchasing compatible tn450 toners the manufacturer would have already reset the physical toner cartridge (usually a physical switch on the toner cartridge) if needed.
If you feel like saving even more and have the time you can even get a toner refills for the TN450 and TN420 laser cartridges though refilling toners can be messy and requires some research on how to do it properly, usually it’s easier just to go with compatible toners.
