Howdy - certainly is. You can find the drivers for Windows 7 here:

Hi,

You need to install the 64 bit driver for Windows 7.

Let's start here: HP C7100 Series Support

You may want to bookmark this page for future reference.

Click on Software & Driver Downloads. Then select your OS from the drop-down menu: Windows 7 (64 Bit). You can download the software or order a CD...or both if desired. If you do not have broadband, forget downloading because the file is almost 300MB.

Here are my suggestions for downloading and installing:

When you get the download window, select Save. This will open a window to direct where to save it. On the left side, click on Desktop and then click the Save button. This will download the file to your Desktop.

When the download is complete, close all programs. Make sure you remove all previous software that you attempted to install. Verify the printer is NOT listed in your Printers folder.

Disconnect one end of the printer's USB cable. Leave it powered on though. Reboot the computer and again verify software and the printer are gone.

Double-click the file on the Desktop that you downloaded. This will begin the install process. Connect the USB cable when prompted.

That should get you going.

Thanks for using Fixya.

hi!!!

try to re-installed your HP Photosmart C7100 driver

or email [email protected]

Do a power drain. This is done by pulling out the power cable and then holding the on/off button for a minute, then putting the power cable back in (this didn't work).

Then we did a master reset. Unplug the printer, then pressing the help and ok buttons simultaneously plug it back in. This sorted it. :) 

For me it works!! 

Try uninstalling the driver and reinstall the latest version for your printer. You can find the latest version driver for your OS from the HP website downloads page.: http://hp.com

Make sure that you use only genuine HP inks and not refills/generic cartridges, which can also cause this issue.

If neither works, try HP tech support for a resolution, or go through their FAQ pages for your printer.
