that would indicate that the printer in question does not support telnet.

if you are looking to close the FTP service, is the service running on that printer?
also, if you browse the printer, can you see what services are running on it that way?

you CANNOT telnet to a windows-only printer, period.  Telnet is a system level interface at the OS-DOS level, and windows-only printers cannot interact with anything but the WIN GUI that recognizes their drivers, designed for the windows DLL calls.  If this printer is a windows only one, you can't telnet to it.
