Printer Troubleshooter

[pirate]

I have a Hewlett Packard Deskjet 692C and it is not printing correctly, I have just replaced the ink tank in it and what happens is when I try to print something, it starts to print, but instead of what it needs to print, it prints a whole lot of little characters that look like tiny little emoticons all over the page, eventually it will print a letter or a number here and there. What can it be?
