Using FTP Printing 33
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 only
one 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. Although
some clients may attempt to autonegotiate a transfer
type, the default is ASCII. 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.
If the connection is successful, the HP JetDirect model
and firmware version will be displayed.
After a successful connection, the user is prompted
for a login name and password. The default is the
client’s login name. The JetDirect FTP server will allow
any user name. Passwords are ignored.
If login is successful, a message
230
will be displayed
on the client system. In addition, the available
HP JetDirect ports for printing will be displayed.
HP JetDirect external print servers with multiple ports
will display all available ports, with Port1 the default
port. To change ports, use the FTP
cd
(change
directory) command. For an example of a successful
login, see “Example of an FTP Session.”
Ending the FTP Session
To end an FTP session, type
quit
or
bye
.
