Print Server Mode
You can use the SX-550 as a standard TCP/IP print server, which is very useful if you are connecting the
SX-550 to a serial printer. The SX-550 supports the following standards:
FTP
The SX-550 supports FTP binary or ASCII communications. This can be used, for example, to send the
contents of a file from a PC to a device connected to the SX-550 using the FTP protocol. To use FTP,
simply enter the standard FTP command from your PC with the IP address of the SX-550 (for example,
ftp
the standard FTP put command to send the file from the PC to the device connected to Serial Port 1 on
the SX-550.
Console Mode Switching
The SX-550 allows you to dynamically switch the operation of Serial Port 1 from normal mode to console
mode. This allows your device to control the operation of the SX-550 by sending console commands (see
chapter 6 and Appendix B for a description of the console commands).
To switch the serial port to console mode, you must first define a console string. When the SX-550
receives this string on the serial port, it will automatically switch the port to console mode. To define the
console string, use a web browser to access the SX-550 internal web pages. After you log in, click I/O
Port, and then select the desired port (S1 for Serial Port 1). When you get the I/O Port Settings page,
enter any desired character string (for example, xyz) as the Console Mode String. Click Submit to save
your string, and then restart the SX-550 to make the change take effect.
Alternatively, you can define the console mode string using the console command as shown in the
following example:
Part Number 40183-101
192.168.5.50). When the connection is made, enter any username and password. You can then use
SET PORT S1 CONSTR xyz
lpr/lpd. This is one of the most popular ways to print on a TCP/IP network. Check your
computer’s documentation to determine how to set up an lpr print queue. Usually this
simply involves specifying the IP address of the SX-550 as the printer’s address or host
name. Some implementations require a queue name; this name is the name of any of
the SX-550 services. To see the names of the SX-550 services, connect to the SX-550
with a web browser (see chapter 3 for instructions on doing this); after you have logged
in, click I/O Services on the left side of the page.
Port 9100. This method is used to set up a Windows Standard TCP/IP port or for
compatibility with software that supports the HP JetDirect Print Server (for example, HP
Web JetAdmin). To use this capability on Windows with the Add Printer Wizard, specify
that you want to use a Local printer attached to this computer (not a network printer),
and then select Create a new port, specifying Standard TCP/IP Port as the type of port.
It is also possible to change the TCP port number from the default 9100 for compatibility
with other printer manufacturer’s software. To do this, refer to the instructions in the Raw
TCP Connection section of this chapter.
