[cups] problem with CUPS network printing and Zebra ZP505 label printer

[Pförtsch, Franz]

Hello,

in my opinion there is a solution ...

today only pcl is handled as "RAW".

Already rendered datastreams should not be rendered twice:

So, the mime type and mime.conv for ZPL has to be extended.

mime.type

application/zpl			contains(0,128,"^XA")

mime.convs
application/zpl        application/vnd.cups-raw        0       -

This is only a quick hack, but working and helpful.

Regards
Franz

yes, and that's exact the problem I had with many other printers (not only barcode ones).
And the exactly the way it was possible to fix them.

And developers answer was just "don't apply ppd's twice".
But, as you mentioned, it is not always possible to do that because of such conditions.

And, unfortunatelly, it is still no CUPS-side solution.

Only way is to manually patch PPDs :'(
