From d6a73ad85bff4867b48d12fa68479812f682ec0a Mon Sep 17 00:00:00 2001 From: Simo Sorce Date: Thu, 22 Apr 2010 19:30:11 -0400 Subject: s3-spoolss: Removed the Phantom DeviceMode. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This was a hack that required a special client from HP. The client code has never been released and was discontinued, so this code was just dead weight.
