I happen to know a thing or two about printing, PDF, PostScript, PJL, Fonts and related stuff.

Also familiar with some bits and pieces of Linux, Unix, Samba and Solaris printing. Not to forget bash programming and Windows cmd.exe batch scripting. I also do consultancy in these topics.

If you want, I share some of this knowledge here and on Stackoverflow (SO). Just click to browse for all.

@kev: Your command doesn't exactly do what @gasko peter wanted. You should have used -extend 520x352. +1 for the 'right direction' though :-P

Add [imagemagick] tag, because the problem can possibly be solved with this tool.

@random: This question led me to do some research about the topic, and I found some interesting options to persue. The most interesting one is using ImageMagick for this, and it seems surprisingly simple. Unfortunately your closing of this does not allow me to post my answer.

@random: Why has this question been closed?? Why should this topic solicit 'debate, arguments, polling or extended discussion'?!?

comment Why do some PDFs lag in Adobe Acrobat?
'Original PDF specification even allowed for the embedding and execution of arbitrary binary & executable files'. -- This is not correct. Yes, nowadays you can embed arbitrary files. But you cannot execute them. And this was not in the original PDF spec, it was added to later version specs. Yes, you can execute: but only JavaScripts. (This makes it possible for hackers to exploit this feature -- but that was not in the spec. :-)
