I had an issue as well, once you download their software it troubleshoots.
also try to press the WPS button on the back of your home router when looking for a network on the printer.
A:AnswerI am not sure about the speed of the 8620..This printer does up to 19 ppm black and 14 ppm color..I have found it to be very fast and sure..the load time is just a bit slow for long documents ..
A:AnswerWith magic jack phone or something like it you can. Also scan the fax to the computer and there are a number of different sites on the internet to do that.
A:AnswerI don't have this issue with mine. Please consider unplugging your router and modem for like 10 minutes then plugging them back in. Also how close are the router and printer? It is possible a signal booster may be needed. Perhaps contacting HP is a good idea, too.
A:AnswerIt works with a Samsung Note II and Samsung s3, so I picture a s4 is a given.. just load the HP Printer app on your phone and you are ready to go.
