I can imagine, i'm pretty sure the RefCardz follow standards, I'm not so sure whether Linux does.

In any case, to visualize the printing result, printing the first page of #14 (both from Evince and Okular) I get about 1.5cm as top margin shows the bottom of the "DZONEREFCARDZ" logo (unreadable... only +-3mm is there), same with the NetBeans logo. Interestingly enough, I have another 3cm on the bottom, but everything prints until the end.
Anyway, just annoying I guess, I will figure out something; was more like targeting on someone that has/had the same problem and figured out some 'standard' settings.
P.S.: Enabling the 'scale to fit' setting systemwide now shows me half the DZone Refcardz logo and 'almost' all the NetBeans logo.
