i have just installed an hp officejet 6700 and using a imac and wireless network to print.

i get a yellow triangle next to the printer icon on the mac while the document is printing.  Not sure what this means?

What version of OS X?  What router?

[MAcambridgehank]

version 10.7.4  and I am using an Apple Time Capsule.

OK, great, thanks.  I assume that the printer is connected wirelessly, not to the USB port of the Airport?

Print a Wireless Network Test from the Wireless menu on the front of the printer.  Does the printer indicate it is connected wirelessly?

[MAcambridgehank]

Yes, the Test Results show the printer is on my network.

[PrintDoc]

OK, great...and there is no USB cable connected to the Airport, right?

Download and install this: http://support.apple.com/kb/DL907

Reset the printing system:

- Go to System Preferences > Print & Scan
- Right (or control) click in the rectangle listing your printers and select Reset Printing System.
WARNING - this will delete ALL of your printers!
- Select the plus sign to re-add a printer. Select the Defualt tab on the top of the window. Look for the printer, select it and wait until the "Add" button becomes available. Click it.

The yellow triangle still appeared when I printed a page after installing the update.

[PrintDoc]

OK, click on the triangle - it is probably a low ink warning.

Alternatively, go to Apple menu > System Preferences > Print & Scan. click the printer and choose Options and Supplies.

[MAcambridgehank]

All cartridges are full and triangle is still there.

Go to Apple menu > System Preferences > Print & Scan.  Double click the printer.  On the resulting window, is there an error indicated?
