B 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
on page 61).

Requirements

FTP printing requires TCP/IPv4 client systems with FTP that complies with RFC 959.
NOTE: For the most recent list of tested systems, visit HP online support at
support/net_printing.

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 (default is 270 seconds). You
can set the idle timeout using various TCP/IP configuration tools, such as BOOTP/TFTP, Telnet, the
printer control panel (see
Web server (V.38.xx) on page

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 server
