[Tugindia] Difference between DVI,PDF,PS printed files

[David Owen]

Hi, Everyone, 

I have just noticed that there is a difference between the hard copies of
DVI, PDF and PS files. The printed DVI is cool. The printed PDF in OK but
the font is smaller. The printed PS is shifted "upward" on the sheet.

Can someone tell me why this is so?

Thanks.
