Hi Harley,
It is currently not possible to change some printer properties through PrettyCode.Print due to a limitation in the third party component that is used for printing. This is something that will be adressed in future releases.
As for the strange icon, I haven't come across this before so I will pass this case over to one of the developers to see if we can reproduce the problem.
Hope that helps,
