Hi
This was a workaround from a previous post on the same subject.
Thank you for the tip about the Photosmart 7200 drivers, it worked great.
Here is a step by step description of how to install.
1.) Go to device manager and make sure you remove any reference to the Photosmart 1215.
2.) Go to printers and manually install, right click in the open printers window and choose Run As Administrator>add printer.
3.) Add a local printer using the existing port: USB001(virtual printer port for USB)
4.) In the next window choose Manufacturer: HP, Printers: HP Photosmart 7200 series.
5.) Then hit next and away you go, you should have the little window asking if you want to print a test page, click yes and if all went as well as it did for me it should be printing a test page.
PS Make sure the printer USB is plugged in and printer is turned on.
