I am experiencing an issue where when I use a color with an alpha that is not at 100% the entire page will not print.
For example
I also have some test text printed on both.
If p1 does not print r, p2 prints r using c2, p2 prints fine.
Here is a sample application to demonstrate this:

This is caused by a java bug: https://bugs.java.com/bugdatabase/view_bug?bug_id=7146409
A workaround is to print a rectangle on the first page with width and height set to 0 but with the graphics color set to a color with alpha less than 255.
