HP Instant Ink Hewlett Packard Instant Printer Ink program Made my expensive regular ink cartridges unusable because I used them while enrolled in Instant Ink.
I enrolled in their Instant Ink program and then cancelled it, before ever receiving any Instant Ink cartridges.
Then found out my printer won't print - my regular extra large ink cartridges now will not work, because I used them while enrolled in Instant Ink.
So I have been robbed of the cost of those cartridges plus the time and trouble to replace them. Ripoff!!
