Firstly, you need to know that with HP Photo Creations you can print only photos (JPEG, PNG, GIF and BMP). In order to print one page from a group, launch the program and from the Prints drop-down menu, select a size:
After that, press the green Personalize and Print button and click Add Photos. Then press Browse This Computer, navigate to your files, select them using the Select All button and click Open. The program will display the entire group. If you want to print only a single file, check the box next to the file you want to print:
After that, configure the printing settings using the Advanced Print button and press Print:
If you have issues, I recommend to contact HP Support team.
