Go to your local stationers, or printers, and buy a packet of CD/DVD labels--the labels are universal so they'll work on both formats; these labels can also be found, and ordered, over the Internet. Buy some publishing software, in which you can design CD/DVD labels, or download the software from one of the many Internet sites that offer a download.
Design your label using your publishing software; the design process will differ depending on what software you are using. Choose CD/DVD label template option on the program, type in text in the boxes provided and upload pictures that you wish to appear on your label.
Turn on and connect your printer to your computer. Put your blank DVD/CD labels into your printer's paper-feed tray.
Click "Print." Input the label's product information if your printer software requests it; this will ensure that your label is properly lined up when printing.
Take the printed labels out of the printer. Peel them off individually, line up the label with the CD or DVD and carefully stick the label down.
