Try to do not specify paper size on ghostcript, in some countries there=
 exist=20
a paper size so called "oficio" too like to "legal" that has about 1 in=
ch=20
(2cm) of less paper than "legal" we use to increase in our documents th=
e=20
footer margin to fit on "officio", I don't know how this should be=20
translated.

And why you do not try to use psutils, for doing everything including t=
he=20
join, and later just convert ps to pdf.
