I hav buy hp photosmart model printer 6 month back,since day 1 its wireless feature not working,till now its not working,many times engeneer comes and goes,one of them said router is not compatible pls buy BELKIN ROUTER AND MODEM and i followed them,i spend lots of money and time(more pricous). Into this printer

If hp do this things with their customers it means hp is not capable enough to solve problems with in warrnty period.

I m suffering from day 1,and now its 6 months,but problem still same.
