I found on you forum that someone else had this problem and was recommended to upgrade their printer driver. I upgraded mine and I have upd-pcl6-x64.5.6.0.14430 dated 12/15/2012 and it still fails.
The error I am getting is "The value '-1' is not a valid value for the enum 'PaperSourceKind'"

Can I set a default value for the paper source kind to get around this problem? If so, how do I set it? I tried to, but it's read only.
