HP Jetdirect 310x - Print Server For Fast Ethernet User Manual page 110

Using standard FTP, a control connection is opened by the client to the FTP server on the
HP Jetdirect print server. FTP control connections are used to exchange commands
between the client and the FTP server. The HP Jetdirect print server supports up to four
control connections (or FTP sessions) simultaneously. If the number of allowed
connections is exceeded, a message indicating that service is not available will be
displayed.
FTP control connections use TCP port 21.
Data Connection
A second connection, a data connection, is created each time a file is transferred between
the client and the FTP server. The client controls the creation of a data connection by
issuing the commands that require a data connection (such as FTP ls, dir or put
commands).
Although the ls and dir commands are always accepted, the HP Jetdirect FTP server
supports a single data connection for printing at a time.
The transmission mode for an FTP data connection with the HP Jetdirect print server is
always in stream mode, which marks the end-of-file by closing the data connection.
Once a data connection is established, the file transfer type (ASCII or binary) can be
specified. Clients may attempt to autonegotiate a transfer type, and the default transfer
type depends on the client system (for example, Windows NT may default to ASCII,
while UNIX may default to binary). To specify the transfer type, enter the bin or ascii
command at the FTP prompt.
FTP Login
To start an FTP session, enter the following command from a MS-DOS or UNIX
command prompt:
ftp <IP address>
where <IP address> is the valid IP address or node name configured for
the HP Jetdirect print server.
