I have an HP Deskjet 5740. it’s a color printer with a color cartridge in it.
Whenever i try to print something in color, it doesn’t let me. The paper comes out blank.
I’ve checked the ink levels and the color carttridge is full, so it’s not out of ink.
But I don’t know why it won’t print in color.
Someone help???

I was given a hp photosmart c3180 printer. This is my first one and besides having difficulty in setting it up I dont know what kind of ink and paper it needs. What kind of ink and paper does it need? How much does each coast and does it last awhile? Is there any website that I can find a manual so i can figure out how to use it? I was not given this stuff.
