Install printer without using disk,

What Operating System on your computer do you have, what is the Manufacturer and Model of your printer and how is it connected, parallel cable, USB cable, or Network.

This information is needed to provide the most useful help.

If you search online for the driver for the specific model of printer download and install it should generally get a printer working. Though without the information above I cannot say this for sure because of the many different types of printers and the ways they can be configured.
