I recently upgraded my 5 year old MacBook to a MacBook Air (OSX 10.8.5). With the old Mac, I was able to connect to the Workcenter 7535 using accounting id's, but with this newer Mac and the same configuration of ID's, I'm unable to print. The 7535 prints out an error page stating, "This job was deleted due to invalid accounting id's". I run virtual box and Windows 7 for some specific software and using the same accounting id's, I'm able to print from the Windows side of my computer. I need to be able to print from the Mac side. Currently using downloaded driver version 2.113.0 from the Xerox site. Help!
