Enable AirPrint on Artisan 837

STILL getting "No AirPrint Printers Found"

First of all, yes this is an AirPrint printer.

So, I picked this up despite everything in my head telling me I didn't need it. Well, I'm tired of emailing things to myself to print, so to heck with it.

I've used Artisan printers in the past and know their quirks, but this is my first bout with anything AirPrint.

Full disclosure - Wondows 7 user. I have an iPad 2 and iPhone 4S running the latest iOS (5.0.1, right?) - just checked and there were no updates.

Artisan 837 is on and connected to my WiFi. I can print just fine. I have the latest drivers and went to Epson's AirPrint "support" page to get the latest firmware.

http://support.epson.net/airprint/fw.html

I went to the printer's IP on my network through a browser and setup Google Cloud print and AirPrint. Google is working just fine.

Here is the AirPrint setup...

Bonjour Service Name - Artisan837 (ususally "EPSON Artisan 837")

Bonjour Location - is this like a workgroup? I've tried it blank (defaults to Epson's own thing) and with a custom name

Top Priority Protocol - two choices, both of which I've tried. "Port9100" (default and current) and "IPP"

I've also used the browser interface to check for firmware updates - I'm using the latest version!

Despite all of this, time and time again, I get "No AirPrint Printers Found." And I'm printing from standard iPhone applications - pictures, email, Safari, etc.

Does anyone have any idea what's going on?

Epson's guides make NO mention of AirPrint. The only way I knew to check the FW was an orange insert they taped to the printer. Their site is undergoing maintainance right now and I can't get to any support numbers... not sure they'd help me much, anyway.

Any help would be greatly appreciated. I've been at this for a while, and am... very irritated to say the least.
