Unfortunately, if you are using an older version of CUPS or a non-Linux
system (particularly OSX) then you will need to manually configure the
use of this backend, as the system will automatically attempt to use the
default backend which does not work with these printers.
use of this backend, as the system may attempt to use the default usb
backend which does not work properly with these printers.
To do this, you will need to remove the printer that was automatically
added by your system then manually add a new one, taking care to select
the correct backend ("gutenprint52+usb"). Instructions on how to do this
are beyond the scope of this document; please see the CUPS documentation.
To check which backend your printers are using, run the 'lpstat -s' command.
Below is an example of its output:
device for Canon_SELPHY_ES1: gutenprint52+usb://Canon/SELPHY%20ES1?serial=221CD10131&backend=canonselphy
device for Canon_SELPHY_ES3: usb://Canon/Canon%20SELPHY%20ES3
In this example, the SELPHY ES1 is using the correct gutenprint backend, but
the ES3 is using the incorrect 'usb' backend. For the ES3 to function
properly, you need to configure it to use the correct backend.
The most expedient way to accomplish this is to remove the printer via your
system's printer configuration interface, then manually add a new one, taking
care to select the correct backend ("gutenprint52+usb"). This backend name
is present in the device URI for the printer, as demonstrated in the above
example. An alternative to the system printer configuration interface is to
use your local system's CUPS web interface, if it is enabled. Step-by-step
instructions for using any of these interfaces is beyond the scope of this
document.
Once the printer is properly configured, this backend will be automatically
invoked as needed; the user will never invoke the backend directly.
