According to the open ports it seems that the router supports printing only via IPP. Neither socket nor LPD is available. Perhaps one can print also via SMB, but often the SAMB port (139) is only open for NAS (network-applied storage) functionality of the router.
Port 631 only accepts IPP, the ports 2222 and 9000 are not for printing.
