I just got an Envy 6400e donated to my non-profit. I have it set up, loaded with paper, ink cartridges installed and full, and connected to my wireless network. I try to print a page and it says it's printing--waiting for job to complete, but nothing comes out. In HP Smart it says, "Printer cannot print." No reason, no error code, no light on the control panel. Perhaps this is why someone would donate a virtually unused printer.
