Top equipment, toner flop

In a nutshell, I can say that the print results are very good. The scanner is better than expected and the wireless integration worked well easily. Overall, the hardware is very well made and the print results on good paper are impeccable.
What annoys me greatly, however, are the absolutely outrageous toner costs. The toners are provided with a chip, which include the pages. So just imagine, you print a page A4 completely in black and just a punctuation mark in red, so one side and the red toner are on the chip, the black toner billed page.
With the original equipment, the unit is equipped with low on toner. After three weeks, the printer was crying out for toner.
Original toner is very expensive. It is available here in the currently set for 299.- to buy. Comparing this with the purchase price!
The unit itself gets from me five stars for print quality and ease of use, the operating policies of Hp gets me no point why only three stars.
