Attention! Not easily compatible !!!

Ordered for a laser printer Samsung ML 2955 ND Toner. (Bought about 6 weeks ago!)
When using the "Tonerkatusche is not compatible" is done!
De Customer Service Print Express said that this ad is for newer models so.
Now I get a chip for top sticking to the Katusche.
Let's see if it works !?
Delivery and packaging are top but !!!
Only useless if the part does not fit!
Get the complete line with improvement!
The delivery of the chip came quickly, as promised.
Now I have glued the chip and lo and behold it works! But unfortunately, only very briefly!
(Another tip: do not go automatic updates The printer installation, since Samsung is always something new
install and then go no longer the counterfeit toner! That's me, however, unaware noticed.)
So nothing against Printer-Express! Top service !!!
Addition:
Unfortunately, it was only 50 pages long with the glued-on chip,
this made the printer pretty annoying grinding and squeaking noises.
Schade, set 30 euros in the sand! I will invest again in original cartridges.
So be careful with the part!
One more addition: Have now a genuine toner used and the works acoustically and technically correct! Now the printer is operating as after purchase.
Conclusion: For newer printer models of toner offered here is not just a flat rate compatible!
