It is possible to buy various non-original toners. I've tried it a few times and it's not worth the small money. It works here, delivery fast and quality at the level needed.

From the first time the printer reported "Out of toner". I ignored it, thinking it was normal for a non-original toner. The printer printed for a while, however, it didn't last long and the toner ran out completely very quickly. Unfortunately, I didn't count the number of pages. Our load is still similar (home use, max. units of A4 sheets per week with normal coverage), but for comparison - the life of the original Brother 2411 in these conditions was about a year and a half, the original Brother 2421 over two years and this non-original -Alza 2421- was gone in less than three months.
The price at acquisition, but.
Apparently insufficient toner supply

DO NOT buy at a price higher than 600 CZK!
None
He didn't last long enough
For a price higher than 600 CZK, it is expensive to the point of woe!
