Barcode Writer in Pure Postscript is, zoals de naam al overduidelijk laat zien, een barcodegenerator voor level 2-Postscript. Een barcode wordt volgens de specificaties van de gebruiker aangemaakt door de 'postscript interpreter', bijvoorbeeld een printer of Ghostscript. Het programma ondersteunt diverse formaten, zoals code 128, isbn-13/10, Maxicode, pdf417 en zelfs kix, dat door TNT Post wordt gebruikt. Voor meer informatie verwijzen we jullie door naar deze quick guide, en een webbased frontend is op deze pagina te bewonderen. Terry Burton heeft een nieuwe versie van Barcode Writer in Pure Postscript met 2010-01-27 als versienummer uitgebracht. De lijst met veranderingen sinds de vorige vermelding in de Meuktracker ziet er als volgt uit:
Version 2010-01-27:
The list of FNC1 exempt application identifiers in GS1 DataBar Expanded was fixed.
Version 2010-01-26:
A bug in the numeric encoding of the general purpose field of GS1 DataBar Expanded symbols was fixed.
Version 2010-01-15:
Support for UPC-E1 was added to the upce encoder.
Version 2010-01-05:
Converted to a set of PostScript named resources rather than a procedure list.
Version 2009-11-15:
A bug in the symbol selection algorithm for QR Code was fixed.
Ensure that auto-encoding a micro-format QR Code symbol fails rather than produces a full-format symbol.
Version 2009-11-06:
Convert interleaved2of5 encoder to use barratio and spaceratio to set the narrow to wide bar ratio.
Version 2009-11-05:
Ensure that the UPC-E encoder does not fail silently when an invalid input is given.
Version 2009-10-13:
