Hi there jdkist1.
Since none of the above has helped then I will need some more information from you regarding the configuration of the C2880.
The first important piece of information is what print controller the C2880 is using. There were two options in Australia and most likely in your region also. There is the internal Canon printer board and the external EFI (Fiery) imagePASS-J1. The J1 is a white metal box that will be hanging on the back of the C2880 and will have two cables connecting to the machine and one that connects to the network socket.
If you are still not sure what you have by looking at the machine, then type the IP address of the printer into your web browser. You will either see a picture of the C2880 or a picture of the J1 with a Fiery logo in the top right hand corner of the web page.
If you have the internal Canon printer board, then we need to determine if you the board supports PostScript. Again, using a web browser, type the IP address of the C2880 into the address line to open the copiers home page. When the page appears, down the left side will be a series of buttons. Click the 'Add. Func.' button and then in the new menu select Custom Settings. With the Custom Settings page now displayed, on the right hand side will be a heading of Printer Settings. If you don't see the heading/link 'PS' and only see 'PCL' and 'UFR II', then you don't have support for PostScript so you will have to use the Canon UFRII v2.00 driver.
You can download the Canon UFRII v2.00 driver via this link...

Note that this driver does not have the iRC2880i listed as a supported model, but it does have a Generic iR C UFRII model and in testing to our iRC3380i, a slightly faster version of your iRC2880i, this worked fine for me.
The last thing I need to mention is Department ID. If you need to use an ID with password to copy, then it is likely you need this also to print. Can you confirm if you are using Dept ID, as there are some extra steps that would be required.
Hope this helps you.
