Much promised, little

I've been looking for a student for an affordable device that in operation (ie as regards the purchase of ink cartridges) as well as in the acquisition does not cause too high cost, and with which one can also scan. This reminds me of this equipment has been recommended. However, I am absolutely disappointed. First of all, I noticed that the prints in the design module are inaccurate, partly lines are displaced or interrupted, which is compared with my previous printer an absolute disadvantage, especially for me, since I almost exclusively work with technical drawings I to Proofs. In addition, the device refuses to print, if it believes the ink cartridge is empty (whether black or color), which I find outrageous. The scanner is of poor quality, the scans are always too bright, I have to edit the brightness and contrast each time. Compared to my previous unit I have spoken often buy more ink. To make matters worse no longer works now, after half a year, the paper feeder.
All in all: If they have a reliable, reasonable and economical printer (and scanner) Search, do not take just this.
