Hey Jeremias,
Bugger on the transparency - I suppose the printer would need to know how to
deal with it.
The reason I'm using postscript (and thankfully no longer PCL :)) - is I
configure tray selections and duplexing, and PDF can't easily help me there.
I will give your latest snapshot a try and see what happens - (I dont think
I have a particularly old version) - and I will see how we go.
As far as the painting of the barcode, I currently store it in the
region-start, config as such;
<fo:simple-page-master master-name="basicPage" page-height="297mm"
page-width="210mm" margin-top="5mm" margin-bottom="5mm" margin-left="0mm"
margin-right="3mm">
<fo:region-body margin-top="0mm" margin-bottom="5mm"
margin-left="8mm" margin-right="0mm" />
<fo:region-after extent="5mm" />
<fo:region-start extent="8mm" />
</fo:simple-page-master>
So I suppose my options in this regard are;
1) see if there is a way to control which region gets loaded when (does
order have any importance within the simple-page-master?)
2) Try to move what I currently use within region-start into region-body
Will see how we go, if you have any advice on my two options, I'd love to
hear it - might save me some time ;)
On a separate note; as I'm learning different printers I'm finding
Postscript command docs - would shortcuts on how to achieve certain goals
using some printers have some value on the wiki ?
Thanks!
Martin

Hi Martin
First problem: PostScript doesn't support transparency. It only supports
image masks using an array of mask colors, but that's not currently
implemented in FOP. PDF has support for both and both are available in
FOP.
The latest snapshot of my PDF plugin supports rendering PDF to
PostScript (and every other output format supported by FOP) but only as
far as Apache PDFBox can handle the PDF minus some potential
restrictions of our PSGraphics2D.
Can't you try to paint the barcode and such after the page content so it
lies above the original content?
