It's time for a new printer. Most of today's printers use one of two methods to create an image. Bubble jet or ink jet printers use ink that is heated and blown onto the page by a tiny stylus. Laser printers use an optical imaging system. Laser printers are generally faster, more reliable, and print better quality images, though there are some excellent jet printers out there.
Laser printers are also more expensive.
First, decide if you need color capabilities. Even boring office documents can benefit from some well-placed color graphs or charts. Keep in mind that printing in color, particularly photo quality, is an expensive proposition. Photo quality prints can cost a dollar a page in ink and paper. And they're not really photo quality.
