My NAS326 was updated to the latest firmware (V5.21(AAZF.11)C0), now I can´t use the print server. I saw in the change log that CUPS was removed. How can I re-enable the print server?

    I think the CUPS has been removed from the NAS package. 
    The printer service will not be available on the latest firmware.
    There is a way to recover the service is to downgrade the NAS firmware.
    You can refer to this article to downgrade the NAS firmware.

    Here are the steps to downgrade the firmware 
    Enable ssh, login as root, and execute
    echo 1 >/firmware/mnt/info/revision
    And now you can downgrade. But be aware of the vulnerability of CUPS.

    Thank you, I hope they restore the print server functionalities. Do you know if it is possible to install some third-party package to implement a print server like in other NAS brands? I bought this device because it was advertised as having a print server.
