FTP printing
FTP is a basic TCP/IP utility for transferring data between systems. FTP printing sends print files from
a client system to an HP Jetdirect connected printer. In an FTP printing session, the client connects
and sends a print file to the HP Jetdirect FTP server, which passes the print file to the printer.
You can enable or disable the HP Jetdirect FTP server using a configuration tool, such as Telnet (see
TCP/IP configuration on page 15
) or the HP Embedded Web Server (see
HP Embedded Web Server
(V.45.xx.nn.xx) on page 63
).
Requirements
FTP printing requires TCP/IPv4 or TCP/IPv6 client systems using FTP that complies with RFC 959.

.
Print files
The HP Jetdirect FTP server transfers print files to the printer but does not interpret them. Print files
must be in a language recognized by the printer (such as PostScript, PCL, or unformatted text). For
formatted print jobs, first print to a file from your application by using the driver for the selected printer,
then transfer the print file to the printer through an FTP session. For formatted print files, use binary
(image) type transfers.
Use FTP printing
FTP connections
FTP printing uses a TCP control connection and a data connection.
Once an FTP session is opened, it remains active until either the client closes the connection or the
data and control connections are idle longer than the idle timeout period. The default is 270 seconds
for a data connection and 900 seconds for a control connection. You can set the idle timeout using
various TCP/IP configuration tools, such as BOOTP/TFTP, Telnet, the printer control panel (see
TCP/
IP configuration on page 15
), the HP Embedded Web Server (see
HP Embedded Web Server (V.
45.xx.nn.xx) on page 63
), or management software.
Control connection
Using standard FTP, the client opens a control connection to the HP Jetdirect FTP server. Control
connections exchange commands between the client and the FTP server. The HP Jetdirect print
