Hi n2scrapping,
I understand you have a Photosmart 6510 that is having issues printing from the Internet. I'm sorry to hear this, but I will certainly do my best to help you!
Which version of Mac or Windows do you have?
Is the printer connected via USB or wireless?
Which Internet browser are you using to try and print the tickets?
Have you tried saving them to your computer and then printing them, or a different browser?
Hope to hear back from you soon :)
