I guess I'm the first to have this problem, though perhaps the bug is posted on BerliOS, their website would not let me finish registering...
When I print, I'm missing 2-3 lines of code between pages. Occasionally I can see the top or bottom pixels of a line that's missing. I upgraded from 8.something to 10.05, but it was no help. I did not find any margin controls, so it seems C::B's automatic margin control is clashing with my printer.
Turns out, hidden away in my printer options, I somehow had my printer set to A4 resize... So I decided to post this anyway, in case some one else has a similar problem in the future. But it would be nice to see more margin controls at least like notepad.exe.
