FTP Printing
Introduction
FTP (File Transfer Protocol) is a basic TCP/IP connectivity
utility to transfer data between systems. FTP printing is a way
to use FTP to send 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 in turn passes the print file to the printer.
The HP Jetdirect FTP server can be enabled or disabled
through a configuration tool, such as Telnet (see
TCP/IP
Configuration ) or the embedded web server (see Using the
Embedded Web Server ).
Requirements
FTP printing described here requires the following:
• HP Jetdirect print servers with firmware version x.20.01
or later.
• TCP/IP client systems with FTP that complies with RFC
959.

Print Files
The HP Jetdirect FTP server transfers print files to the printer
but does not interpret them. For proper printing, print files
must be in a language recognized by the printer (such as
PostScript, PCL, or unformatted text). For formatted print
jobs, you must first print to a file from your application 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.
Using FTP Printing
FTP Connections
Similar to standard FTP file transfers, FTP printing uses two
TCP connections: a control connection and a data connection.
