I finally got tired of the HP printer eating me alive with ink costs. I purchased a Kodak 6150 printer. Surprised to find out I had to install drivers but that is done.
Here is the problem. If I connect the printer directly via USB to the iMac it works fine. If I connect it to my airport extreme I can print from my Macbook but NOT from the iMac.
Was running a trial version of Intego just to see if possible virus was reason for almost incessent presence of the rainbow wheel - no virus. I turned off the Intego and still no luck being able to print from the iMac.
Per the previous question I did double check and sharing for all is on. The little screen on the printer says it is connected to my network. The printer is about 2 feet from the iMac and the airport is halfway between them so no walls etc in the way.
