This solution will walk you through how to connect your computer to your printer. This only applies for the XL and HD series printers. The RAMBo driver needs to be manually installed on any Windows computer used to run/communicate with the printer. For software, please see Repetier-Host - Installing and Setup (Windows).

MAC: If you have a Mac, it will automatically find and install the driver. If you use Repetier-Host as your printer control software, you will need to go to the printer settings and set the "Baud Rate" to "250,000" in order to communicate with the printer.

PC: If you have a PC, you will need to install the RAMBo driver manually using the steps below. Windows 8 and 8.1 will need to start at step 1. Windows 7 and previous versions can start at step 7.
