How do I convert my printer from a USB connection to a wireless connection on Windows?
From the Start menu, navigate to All Programs, select HP, then HP Deskjet 2540 series, and click Printer Setup & Software. Select 'Convert a USB connected printer to wireless' and follow the on-screen instructions. Note that the printer software must already be successfully installed before performing this conversion.
