How can I get my laptop to recognize my printer?

If your laptop won't recognize your printer, check the IP address of the printer. If you set your IP address to be static, then you upgrade your modem, the new modem may not be able to locate the printer. Turn off the static IP setting and let the DHCP hand the printer a new IP address. Then, you can make it static again. Or, you may want to upgrade your router. One of the main problems with wireless printing is using an older router or router-modem combo. Printing sends an incredible amount of data quickly, and that data can get clogged in an older router. If your router is more than 2 or 3 years old, or if you're using the standard router and modem from your ISP, you may need to upgrade that.
