Linux printing is similar. You will be digging trough several layers of abstractions. After finally having had a good look at cups low level driver interface you will find out that it's the printer driver that's at fault. You will notice that the driver is either closed source nad you have no chance of changing what's wrong, or you'll be looking at the drivers code but not be able to fix it, because you do not know your printers non-postscript internal communications protocol. And there's no way to find out. By the way you get there, you'll have wasted several weeks/months understanding all those shell scripts and conversions and the internals of the postscript interpreter(not that it would help you with the problem). Then, you'll go in full denial about your fruitless exploits. After a week you'll think it would be a fine Idea to print those barcodes(or some other documents).... -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
