I re-installed my printer and it will not print. When I go to see what is in the printing box, is says there is an error. Everything is working fine, just will not print.
The first thing to do is to check the printer connectivity on your computer. To do this, simply check the cables and make sure the printer is connected. Secondly, go to Device Manager (Start > Run > devmgmt.msc). If you have an item with a yellow sign, right click it and choose Update Driver. Before that, download the correct driver from the manufacturer's website.

Additionally, check the cartridges to see if there is enough ink, because this could also cause errors with printing.
