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
Requirements

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.
Once an FTP session is opened, it remains active until either the client closes the
connection or the data and control connections are idle for a time that exceeds the idle
timeout period (default is 270 seconds). The idle timeout can be set through various
TCP/IP configuration tools, such as BOOTP/TFTP, Telnet, printer's control panel, the
embedded web server (see
