airprint-proxy's Issues

need additional Info in readme

From README.md it is not clear fo me,
if that library can be installed on iOS (iPhone, iPad) and used there
to connect a network printer (IPP-Protocoll) for printing.
Sadly that network printer is not findable while with iOS AirPrinter-search,
but other systems (Windows,Linux) can print on that printer via WLAN using IPP.

Support overriding the printer DNS IP address

Fantastic project, just what I needed to expose my printer from one network to another via NAT. Windows network printing just worked but Airprint needed this extra helping hand

Just one small feature request: I had to hack addr in resolve.js onLookup to a different IP address, as I am NATing ports to the printer. It would be really great to expose the A record IP address as a command line flag in case it differs from the IP that the local machine running airprint-proxy uses for the printer

Known issues?

Are there any known issues with recent iOS releases?
I would like to use the tool for printers that are in different subnets. They support Airprint and if directly print to them it works, but using airprint-proxy I can see the printer being available, but get an error message when printing.
On the iOS console I can see errors like:

Jul 25 17:52:40 iPhone MobileSafari(PrintKit)[2577] <Notice>: OKI._ipp._tcp.local.: Get-Printer-Attributes failed: Bad Request
