I'm currently working on a IoT project and use a DNP DS620 printer. According to @Solomon, the last CVS code should support its rewind feature, but I can't find any way to activate it. When using the official driver on windows, it provide another print format (5x3.5 N) to use this feature, but cups still give me a simple format list. Is anybody already achieve this or know how to?

A critical question -- do you have the DS620 or the DS620A? The latter does not support rewind. Also, make sure you're using the latest released firmware (1.21 I believe)

But to follow up, there's nothing special needed to activate rewind. If the correct media is loaded, a supported print size is utilized, and the printer claims to support rewind, it is automatically utilized. It's been pretty well tested.

I can confirm you that the printer (DS620) has the rewind function (it's working on windows and mac with the official drivers) and that's the printer is running the last firmware version, but it's not working with Gutenprint 5.2.11 on linux.

You did not properly install Gutenprint 5.2.11; this should read 'version 0.63G'. It even predates Gutenprint 5.2.10, which is 'version 0.48G'. This file appears to be from Gutenprint 5.2.10-pre2.
I'm gonig to guess you're running on Ubuntu, and that you did not remove the system-provided Gutenprint package before you compiled your own.

Oh, pay attention to the output of ./configure -- in the summary at the end, make sure there's a line that says 'Build CUPS dyesub USB backend: yes'. It's likely you didn't have some prerequisite, preventing that from being enabled.

The backend will automatically utilize the rewind mode whenever possible; there is no need to select that mode specifically.
I'm having the same issue with a DS620 and Gutenprint 5.2.11, no rewind for 5x3.5. Is there a trick to activate the feature?

Okay, I'm going to need you to do somethign for me.
as root, run:
BACKEND=dnpds40 /usr/lib/cups/backend/gutenprint52+usb -isn
And send me the output.
That should have sufficient information to tell me if the printer thinks it supports rewind.
Mmmhh, this is the output I'm getting:
And the printer is connected and printing...
Can you repeat that when the printer is not printing?

Yes, indeed!
That might be the solution :) I will try to remove everything, re compile and install :)
Thanks a lot.

Thanks a lot, it's now working as expected.
