iphone/ipad No Airprint Printers Found

[Neo666]

I found a solution online and think it might be useful for other people, as it is no where documented by HP website.

I have recently set up an iPad and printer for a Pre-school who needed AirPrint as a core feature and much to my dismay I came across this same problem and after some research I managed to untangle the problem and I thought I would share my finding as I am sure there are an awful lot of people who will be having the same problem.

These are my finding from other forums.

1.  I note that some forums suggested updating the firmware of printers and whilst in some instances this was the problem in the early days of AirPrint (canon Mg6100/6200 for example need Ver. 2.0 or later) that's no so much the case with new printers.

2.  Some other forums suggest changing to WPA or worse WEP, whilst this might work for some this isn't the problem, more a work round which exposes your data.

3.  Buy an new airport/time capsule, daa!! Very nice but not necessary in this instance!

Solution.

BT Home Hub 3 uses "smart wireless" which is supposed to switch channels when interference is detected, microwaves etc but this means that automatic Chanel swapping happens on the fly.  This system seems to interfere with bonjour and hence AirPrint/AirPlay.

To undo this go to the home hub home page http://bthomehub.home/ You may need to enter the admin password on the removable plastic tab for access.

Select the "settings" tab.

Select "advanced settings" in the sub tab.

Select "wireless" in the suc-sub tab if you like.

In the "channel selection" you will see "Smart Wireless" selected by default.

Set this to channel 11 and select "apply" at the bottom.

9 times out of 10 this will work as everything seems to like channel 11 but if this doesn't work the other favourites are channel 1 and 7.

I hope this helps as I can't imagine how many iPhone/ipod/ipad sporting homes who have Home Hub 3's can't print for this very simple.
