Why does Eagle print everything "thicker"?

I tried Eagle 5.11 on Windows XP, 6.1 on Mac Lion, and Windows XP..

Closed all layers but top layer.. The results are the same on Xerox 3140

package bridges, and the 10mil lines between SO8 package's pins 1 and 2

tends to bridge to the pin 1.. The calibration is OK, I printed 100mm x

100mm rectangle and its good enough..

 

I printed to pdf, and printed the pdf with Preview application on

macosx, this time the results are much better.. I would say "Oh, I can

do that way" but after comparing it with the same packaging, same size

that Proteus Ares produces, I saw that Proteus produces cleaner

results.. It looks like Eagle widens everything..

 

Should I configure anything other than "calibrate" and "black" options

on printer dialog?

Eagle "prints" just fine to Gerber files, which is what you send off to

the circuit board house.

If you need accurate pdf files, perhaps you should see if you can find a

Gerber file viewer that prints?

I process prototypes myself using photosensitives.. There isn't "one day shipment" choise here.. Because of that I need decent printouts as I am using small packages.

I've been working with Proteus without an issue, however this was surprize to me..
