Printing black/white construction drawings.
One of my Sheets has very slightly shaded background (scarcely noticeable), rather than being transparent/white.
This massively increases the print spooling time (other normal documents print immediately).Anyone else had this puzzle?
To clarify: it's the entire printed area--excepting the paper margin--that has the shading, not just the viewport.
And I've confirmed that background is set to white in interactive appearances tab.
