Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I'm sorry to hear about the problem. It must seem quite worrisome.
Is it possible that you bought the XL ink cartridges from a shady supplier?
Ink counterfeiting, odd as it may sound, does exist, in the inkjet printer world. E.g. if your cartridges said 'HP compatible' on the package, then they are refills or remanufactured or otherwise not-genuine-HP-made.
The official HP word on that sort of message is, that if the message does not appear immediately just after you put in the new cartridge(s), then you may simply disregard it.
But I'm not sure what the exact and full error message you see is. Could you please reply (using Reply To Expert) and let me know? I'm not quite sure that I've given you the exact right information on the error message yet, and I'd like to be sure I am advising you accurately.
As for the printer being slow, and not printing in color... those are separate problems, from each other at least. I think we can deal with them separately, for now anyway.
1. no color: does that mean that pictures are printing out in a grayscale or black-and-white version? if so, that might be a setting on the computer. Let me know whether it is printing colors in gray shades, or simply not printing the colors at all.
2. printing slowly: that can be several things. Let me know the basics: is your computer Windows, or Apple? is the printer on a direct USB cable connection, or is it on a wireless connection?
