PDF printer vs PDF export

[Assemblage 0]

When I print a hard copy from pdfs made using the Adobe PDF "Printer" vs exporting to pdf withing VW I get different quality results. Basically, the line quality etc via the Adobe printer is better. But using export is essential for batch tasks. Shouldn't the two pdfs be identical?

Could you post an example here? I get excellent quality exporting from VW.

You got me: I can't reproduce the difference in the hard copy (in this drawing..).

But there are real differences in the pdfs. The VW export is 3 times heavier, and hatches and lines appear feint and slightly 'crumbling' on screen.
