So yesterday I downloaded and installed Lion. Its perfect! but it wasn't complete without my printer. my Lexmark x9575 AIO printer was not printing wirelessly. I immediately contacted Lexmark Support and was helped and fixed. Now right now i would like to help you all set up your Lexmark 9500 Series printers to print wirelessly.
1. He told me to download both OSX 10.7 support softwares that can be located here: http://support.lexmark.com/index?segment=SUPPORT&userlocale=EN_US&locale=en&productCode=LEXMARK_X9575&page=product&frompage=null#1
You must download both.
2. Secondly you must install the printer driver and then the wireless setup assistant.
When you get the setup window for the wireless assistant follow all steps and press done when you have finished. (dont go into system preferences and add yet)
3. ok now go into safari and click on the bookmarks tab and click on the 9500 Series under the Bonjour services.
4. Copy the address of your printer.
5. Open system preferences and add a printer, go under IP printer, now paste the ip addressed you copied under the "Address:" line. Also make sure you select HP Jetdirect - Socket.
You can name the printer anything you would like.
6. After you press add the driver will load and the printer will connect to your computer.
7. Now it should be set up and ready to go. Note: once you start printer starts printing you queue window will show an error saying ink is out. ignore that message unless you know your ink is really out.
'Well thats is, your Lexmark 9500 Series should now print wirelessly on OS x Lion v10.7.
