A new printer can often be installed without encountering any problems. (Note that you should uninstall the software for the old printer first, if you had one.) Wireless printers can sometimes be tricky, with lots of options to select on the printer control panel. They can also be unreliable if not set up properly. It is possible to share your printer even if it is not wireless, so you can print from more than one computer.
If the setup process doesn't go smoothly, or you would like some expert help to ensure correct installation, contact PC Rescue.
