[Gimp-print-devel] duplex, two-/double-side printing for all Epson Stylus Office BX printers (Debian Bug#951410)

[Didier 'O. R. <od...@de...>]

Hello from Debian,

Twinker reported the following to the Debian bugtracker, and this should 
really be fixed upstream; could this be integrated in gutenprint?

Best regards, OdyX

Hello,

I am using an Epson Stylus Office BX535WD printer. Most Epson BX 
printers are able to print two-sided (duplex, double-sided, 2-sided).

There is no possibility for the user to define duplex in the web 
configuration of cups (localhost:631) nor in any application, because 
the generated PPD printer driver file misses the duplex option although 
the driver itself reports 2-side printing:

To correct this and to be able to select duplex printing the underlaying 
XML definition files which generates the gutenprint printer driver PPD 
must be modified:

Take a look in the XML file 
"/usr/share/gutenprint/5.3/xml/printers/escp2.xml"; most BX printers are 
defined as "model=92".

Patch:
In the XML file
- "/usr/share/gutenprint/5.3/xml/escp2/model/model_92.xml"
the parameter
- "<inputSlots src="escp2/inputslots/default.xml>"
should be corrected to
- "<inputSlots src="escp2/inputslots/default-duplex.xml".

After that the printer driver configuration should be reinitialized in cups:
- delete the current BX printer in the cups web front-end
- stop the cups printing service
- delete the PPD file for the printer from "/etc/cups/ppd/*[BX|bx]*.ppd"
- start the cups printing service
- re-create the BX printer

Now you are able to configure "2-sided" (duplex, two-/double-sided) 
printing in the web front-end.

Regards,
Twinker
