That's pretty decent; got any pictures?  I've stayed at 6-12mil 
trace/6mil clearance on my boards.  I've seen when doing 4" x4" or 
bigger that I needed to surround the fine traces with other toner to 
keep the stock from peeling off the super thin lines. You must of hit 
on an even better toner/printer combo.  What printer/toner 
manufacturer are you using?  1200dpi?

I haven't had any TT magazine paper jams yet in my HP 5L sending 
magazine pages through the envelope feed (1 sheet/time).  I was 
cutting the paper with a paper cutter at first; now I just rip it out 
of the magazine and feed it through directly.

I did a write up of the process a while ago.  Anyway it shows a few 
pictures of what I've done on it.  It was cited on this thread 
earlier:
