Hello. My I use my

hello. My I use my Pixma printer with a Macintosh powerbook running OS 10.5.8, and a G4, running 10.4.11. Within the last month, my Pixma 1420 has started to print a line, then wait twenty seconds before printing the next line, for the an entire page. This occurs with any application (illustrator, in design, Microsoft word), and whether or not the printer is directly connected to a computer or through a router. It's 3 years old. Is it dead?
