I'm running v4.6 of Phped and am having difficulty printing code correctly.
When I just print, it's crowded all the way over to the left.

When I click "line numbers' the numbers overprint the left 2 (or so) characters of the code).

2 images attached....the print dialog box and the resulting printout.

Any ideas?

Yep, sure There was problem like this and it has already been fixed.
Check if you have build 4621 installed.
