[Gimp-print-devel] Question regarding DNP-DS620 printer setting in command line on Linux Ubuntu, able to expand print size width

[Antoine B. <an...@em...>]

Hello Miss, Sir,
I contact you because my company would like to be able to change the 
width of the size of the prints on the DP-DS620 printer on Linux Ubuntu.
We know that DNP company Hotfolder application on Windows and Mac works 
and allows printing with wider widths than the basic formats offered by 
the printer, we would like to be able to do the same on Linux Ubuntu 
version 20.04LTS from the command line.
You can find the Hotfolder app on their website: 
http://dnpphoto.com/en-us/Utility-Apps.
Currently we are using a gutenprint 5.3.3 driver for the DNP-DS620. Here 
are the available options:
