HP Office Jet 'Pro' 7740 - It prints, but thats about it. Tried scan with USB using document feeder - nope, fails to scan properly all pages, then decides it doesn't want to write the scan files to the USB. Tried different USB nah mate, don't want to do that! Installed HP scan software, doesn't see printer, dropped of network again. Three reboots.

I today, for the first time asked it to do more than one thing, and it failed badly! My last HP printer.
