First you need to check for the drivers. If you're using two different versions of Windows, you will need to install the corresponding driver. Second, the print spooling service could be stuck or stopped. You can check that in the Start > Control Panel > Administrative Tools > Services. If the Print Spooler service is stopped, please restart it. And third, check the connection to the printer and your wireless device. Most likely this is the reason that it says it can't print the document. The manual states that the hardware should be checked (cable, drivers, connectivity, etc.).
