I am tryng to print to a Photosmart 610 using Windows 7 - Avery Name Tag label - using Avery stock

I am using an HP DV7-3065dx Entertainment Notebook with Windows 7 trying to print Avery Name Tag Labels to an HP Photosmart 6510 211b - I keep getting a paper mismatch when trying to print. It will print okay when I use an 8X11 inch regular paper but when trying to used the 74520 stock that came with the kit it will not print??
