I purchased HP 4288 all in one printer few days back from online shopping site.
Firstly it took so much time to connect with my computer, printer is not detected by computer.
After many attempts it detected.
When I command to print one of my pdf document it took almost 15-20 second to print one back and white page.
And almost more than 20 seconds to print colored page and the quality of print was also not good.
I don’t recommend anyone to purchase this printer.
