I have a fairly unique problem that I'm hoping someone has a solution: My Airport Network has been working superbly for several years - UNTILL recently. For unknown reasons, one of my USB-connected printers stops printing from either Windows computer connected wirelessly to my network? Here are some details describing my Airport Network configuration:
o Base is AirPort Extreme (2nd Generation). It is then connected to my Internet DSL Router.
o Bridged AirPort Extreme (1st Generation).
o Internet connection is via DSL eXtreme router (working fine).
o One printer connected via USB from AirPort Extreme Base (Canon Pixma 9000). It works fine from any computer.
o One printer "connected" via WIFI-Wirelessly via my Airport Network from either computer (Canon MG6320).
o One printer connected via USB from Airport Express (bridged from Extreme) (HP Photosmart C4150). THIS IS THE PROBLEM AREA!
o One computer is MacBook Pro Retina 15", running OS-X 10.8.3 AND running Windows XP SP3 via Parallels 8.
o One computer is Sony VAIO Notebook, running Windows 7 Home.
When printing to the HP Photosmart C4150 from either Windows computer, ALL OF A SUDDEN, no communications occurs and thus no printing happens! But, when making a print via my Macbook Pro, it will still print fine (while any Windows computer will not)!
When I analyze why, I discover that the Airport Express has (by itself?) has changed from its IP Address that was working fine to a different IP Address that then prevents printer communications from occurring! NOTE: The HP printer is configured in Windows by using a TCP/IP Port that is set using the Airport Express's IP Address. This technique to get printers using Windows to print wirelessly through Airport devices has been used very successfully for 3-4 years and was provided by iFelix.com. It has been an outstanding technique!!!
To get my Windows computers to print again, I have to go into Windows "Add Printer" in Control Panel and REDO all steps that the iFelix Technique describes - this time, I change ONLY one setting: The Airport Express' changed IP Address to be the new/changed IP Address. Then, all printing resumes just fine - until the Airport Express "decides" to again change its IP Address!
As you can imagine, this is extremely perplexing and a pain to do! I've been forced to do this 3 times this year - and I need your help to prevent the Airport Express from arbitrarily changing its IP Address.
ANY HELP THAT EXPLAINS WHY THIS HAPPENS AND WHAT I MUST DO TO PREVENT THIS WILL BE GREATLY APPRECIATED,
