Read the fine print...Lite APP is for testing compatibility before you buy

This Lite version of the APP is only for checking and testing compatibility with your printer. I have an old HP M1522nf MFP which checked out fine and printed their test pages, print and photo, successfully. I then felt it was worth buying the full APP. Much better finding out this way for free than paying $$ and finding it didnt work. Im thrilled...so far, so good.
