HP Deskjet printer buying guide

okay i have a hp deskjet 3820 printer
i was trying to save money by refilling my old ink instead of buying a brand new one.
:/ i tried to insert it back in and the lights for the ink kept blinking and when i check the ink level the color doesnt even show and the black is still very low. HELP :[ i dont want to waste even more money!

HP Deskjet F300 all in 1 series.
In the control panel it says this is the default printer and is ready and has a green tick. but it just won’t print. if i turn computer off then on again then it will print whatever is in the print queue but nothing else.
I am running Vista. I have tried Windows help & support and HP troubleshooting too.
I have attempted to reinstall the printer.
Please help!!
