LibreOffice + CUPS only shows the following printer properties: 

paper size,orientation,duplex,paper tray

for my HP Laserjet 5. I just tried printing a page with all margins set 
to zero, expecting that at least one or two characters would be cut off 
on the left margin but, no, it just left a (guessed 4mm margin all round. 

I can't tell if CUPS knows what the required margins are for an LJ5. 
However, something seems to have decided to use the printable
area rather than the physical page size and to have centred it on the 
physical page. The only think I know for sure is that the CUPS client, 
i.e. Libre Office, knew nothing about required minimal margins. If it did 
know that, then I'd have expected to refuse to set zero margin widths.

My guess, and thats all it is, is that Java would do the same if I'd been 
running an application that printed through cups4j or one of the other 
classes you listed.
