Please help me. I haven't printed on a CD with my HP Photosmart D5160 in a while and I either can't remember how to do it, or it doesn't like the new laptop.

I spent a week figuring this answer out. First Do not use the supplied software from HP for this, unless simple text is okay for you. I personally found the software to try to do everything, but nothing well. If you have even a modest image application: Gimp, Photoshop, etc, create a new image at 4.5 inches x 4.5 inches. Set the ppi to 150 at least, 300 for High Quality and create you 'label' there, then go to print.
1. in print dialog box choose 'Preferences'
2. then choose 'printing shortcuts'
3. then choose 'print on CD/DVD' (DVD icon)
(confirm in papersize on right that you are printing on a cd/dvd)

4Then pull down your CD/DVD tray flap on the HP printer and load up a CD to print on. Align it to the arrows, then press print.

As long as the image is 4.5" x 4.5" it will fill the DVD perfectly --especially if you download a 'Mask' template from any printer --which you could google to find one, but it is just to give you an Idea of your 'safe print' zones, and will really come in handy for high quality labels-- don't for get to turn off that 'mask' just before saving--if it's black, or better yet, make it white, then when you save the final image it will create a beautiful white circular edge on the image so that you can better preview and so that you won't waste ink!
