i was given a hp printer 3820 and when i try to print it just shoots the paper out but it doesn't print anything the cartridges don't even move. its kind of loud i am not sure if that is because its old or if it broke. But when i try to print i saw the ink was low, now i was wondering if when this hp printer is low on ink if it just wont even move the ink cartridges to even try to print. My other printers that i have had will print even though it is low on ink it just wont look good though. i don't want buy ink and then have it not work and i just lost money. Please help, thanks a lot!!!!
