DPI Resolution / Don't get it :(

[Sebastian Vorköper <sv fogman de>]

Alright,

after all, i have some trouble with the physical paper size thing.

Should i always use the phys. paper size? even when i print to a 1200
DPI printer or a 72 DPI Postscript document?
(The Information of a bitmap/picture doesn't seemed to get lost!)

If so, that means that the calculation of the phy. paper size is always
done with 72 DPI and i don't loose information of a "big" picture when
printing to a "real" printer on one page?

Thanks,
Sebastian Vorköper
