Printer HP 8500 Pro Wireless. Bought 2011 at specialist retailers. Use HP printers since about 1993. Several inkjets for various applications. Could I actually rarely complain about print quality and reliability. An older and simpler 1310er does it as a backup device in the office still without problems. Unfortunately, the good times with HP printers now seem to be over. This was now the third new printhead (dearly for confidence in old qualities). And he's three months already over again. Any change eats the allegedly favorable Tintenpatornen on literally. Now have the final line drawn and bought a device with similar functions from another manufacturer. Whether better remains to be seen. From the purchase of these print heads, I regret to advise. If the trouble starts times, he will not stop and will only cost money. HP pity that you no longer can and makes fun of customers.
