good quality, large, heavy and expensive cartridges

Previously I had the Canon IP 90 and was satisfied.
The Canon is less a little faster and a little less accurate when printing.
The HP weighs almost twice is twice as large and in my opinion for
the Außendiesnt with more than 4 customer appointments per day conceivable ungeeigent because bulky and heavy.
The cartridges cost (with an integrated print head) for Druckerzubehoer.de 21.97 for 15 ml color and 15.97 for 20 ml black.
That makes per ml color for the color cartridge 1.45 (for No Name cartridge !!!) Canon 0.33 per ml. The HP cartridge costs per ml 4 (!!!) times as much.
Black is still 2.2 times more expensive than the Canon.
With a printing speed of 20 pages per day that goes right into the money.
If my boss had not arranged the HP I would return swap immediately.

The processing is just like the print quality, the battery performance and the design very well.
Bluetooth works after initial problems properly.

For someone who has to haul the machine every day, and the cartridge itself pays the printer is in my opinion not suitable.
Therefore only 3 stars although no eye defects have emerged.
