RE: [postscriptbarcode] Right aligning barcodes

j...@optifacts.com (John H) — Tue, 11 Nov 2009 17:32:15 UT

The way I've been achieving this lately is by rotating the barcode 180
degrees and setting x,y coords as needed... Basically printing it
'upside-down'. Barcode scanners don't seem to complain and our customer
base is happy.

Right aligning barcodes

I'm using Code-128 and wish to right align the barcode against the

When printing text using Postscript I can use the stringwidth function
to achieve this.

Is there any recommended or suggested way to achieve right alignment

Hi,
Thanks to some excellent work by Chapman Flack, in the form of
net.anastigmatix.Packager [1], the named resource delivery format for
BWIPP [2] is now more compact and contains DSC compliant comments,
which means that it should be more digestible for document management
software.
I've refreshed this example [3].
