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 14) or the HP Embedded Web Server (see HP Embedded Web Server (V.40.xx) on page 64).

Requirements

FTP printing requires TCP/IPv4 or TCP/IPv6 client systems using FTP that complies with RFC 959.

NOTE: For the most recent list of tested systems, visit HP online support at www.hp.com/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. 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 14), the HP Embedded Web Server (see HP Embedded Web Server (V.40.xx) on page 64), 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 server supports up to four simultaneous control connections (or FTP sessions). If the number is exceeded, a service not available message is displayed.

FTP control connections use TCP port 21.
