Phaser 4500N printing garbage

Under Windows 8.1 64-bit with the latest printer driver from Xerox.com, the Phaser 4500N printer frequently prints out garbage characters from Internet Explorer 11 and Windows XPS Viewer.

The printer has to be turned off and the paper removed from the paper path.

Rebooting sometimes, but not always, can allow printing to come out correctly.

I read a web page that mentioned that, in the registry, the DependOnService key shows RPCSS http.

Would a firewall be causing this ?
