'fooba'
'duuba'
'dooba'
'du'
With quotes
'fooba'
'duuba'
'dooba du'

You can see that "dooba du" will be used as two arguments with $@, one arg with "$@" which is kinda strange 'cause $@ sould do exactly this (quoting arguments), but it is reproducable on a number of systems.

Have you tested using

arg=''

for i in "$@" ; do
j=`echo $i | sed 's/ /\\ /'`
arg=$arg $j
done

a2ps ... $arg

or something similar with escaping, not quoting, the strings? Or using both? (arg=$arg '$j') as it could be a similar problem with multiple scripts run after each other?
e.g. a2ps running "a2pdfwr $@" or whatever.

I can't test it myself, my ps2pdfwr seems to work
