How to Connect a Printer to a Computer

Position your printer. If you have a laser printer, allow a few inches of space on all sides for ventilation. Ink-jet printers don't require ventilation.
Buy a bidirectional, IEEE 1284-compliant parallel printer cable. (Printers rarely come with cables. See 'How to Buy a Printer Cable,' under Related eHows, for more information.)
Shut down the computer, but leave it plugged into the surge suppressor.
Compare the connectors at the opposite ends of the cable.
Attach the 25-pin end of the cable to the parallel, or printer, port on the computer. (The plug will go in only one way.)
Tighten the hand screws securely.
Connect the other end of the cable into the printer's socket.
Latch the retaining clips (on most printer ports).
Plug the power cord into the printer and into the surge suppressor.
Turn on the printer.
Install cartridges according to the printer manufacturer's instructions.
Turn on the computer.
Install printer driver software according to the manufacturer's instructions.

How to Find Out What Kind of Ink Cartridge I Need for My Printer

Locate the existing ink cartridges inside the printer. Remove the cartridge and find the correlating identification number on the outside casing. You can order a replacement cartridge using that exact number either online or by locating the cartridge by number in a store. Inkjet printers require separate ink cartridges for black and color ink cartridges, making it necessary to buy two replacement cartridges. In some cases, your printer may require separate ink cartridges for all four colors: Cyan, Magenta, Yellow and Black, necessitating four replacement cartridges.
Locate the name of the printer by inspecting the outside of the actual machine. The name of the printer and any identifying description should be on the front of the machine, or at the very least, on the back where the cord extends from the machine. For example, if the front of your machine reads 'HP Photosmart 8250' jot that information down for easy reference when going to purchase a replacement.
Log on to the office supply website of your choice. Locate and select the 'Ink & Toner' section and enter the make and model of your printer. Evaluate the options provided, while determining if you need black, color or both ink cartridges. Purchase accordingly.
Drive to an office supply store and ask a sales associate to help locate the replacements quickly. Make a note of the ink cartridge number for future purchases.

How to Print on a DVD With a Laser Printer

Ensure your laser printer is CD/DVD-compatible if you haven't already. If you are unsure, consult the manual.
Open your printer control panel. For most printers, you can do this by selecting 'Print' from any application, then clicking 'Settings' or 'Preferences.' Some laser printers also install a little printer icon in the lower-right corner of your screen.
Look for and click on a tab or link labeled 'Paper Type,' 'Paper Size' or 'Media.'
Click the drop-down box and select 'CD/DVD.'
Insert a printable DVD into your printer. You'll know a DVD is printable because the top will be white instead of silver or colored. CD/DVD-compatible laser printers will have a special slot for this. Be sure the disc is facing the right way or the printer will print on the recordable side and ruin the disc.
Open the image or document you wish to print on the DVD.
Click 'Print' from the application's 'File' menu.
Click 'Print.'
