IPhone – Print adressbook from iOS without computer

I had the same problem and this is what I did to fix it:

1. Go to http://localhost:631/

   If you get the "Web Interface is Disabled" message, run cupsctl WebInterface=yes in Terminal.

2. Choose the Administration tab.

   

3. Click Add Printer.

   

   If you are required to login, use a local Administrator account.

4. Select the printer (in my case it was automatically found).

   

In both scenarios, using the IP or machinename.local address of the Mac will only give you the default website on that Mac. Your web apps are all at the top-level so Nginx is expecting different hostnames in the request. Problem is, these hostnames end in .localhost which isn't being resolved by DNS, so the iPad doesn't know where myapp2.localhost is, and the request never reaches Nginx on the Mac.

You've already gotten around this problem somehow when testing from the Mac. Maybe you've edited the /etc/hosts file, or you have a GUI that does that? However, you can't modify the iPad hosts file without jailbreaking.

A simple workaround is to change the default website in Nginx to the webapp you want to test from the iPad - then you could use the machinename.local address from the iPad. But you have to change this every time you want to test a different webapp.

More complicated workarounds would be to a) configure Apache on the Mac as a proxy server, and configure the iPad browser to use that as its proxy; b) set up a DNS server on your local network; c) use instead the iPad simulator on the Mac, while modifying the /etc/hosts file; or d) jailbreak the iPad and modify /etc/hosts.
