PAD Ser vices

Remote PAD Printer Support (x29printd)

Chapter 6144

Examples

x29printd and lpsched Operation

For this example, a printer (a RuggedWriter) is connected on port 5 (or

B1 on HP 2335a PADs) to a PAD whose address is 4085551203. The

address of the printer in this case would be 408555120305. In the PAD

device local configuration, port 5 must be downloaded with:

parm_no: parm_value;1:0; 2:0; 3:0; 4:10; 5:0; 6:0; 7:0;

8:0; 9:0; 10:0; 11:14; 12:1; 13:0; 14:0; 15:0; 16:8;

17:24; 18:0; 19:1; 20:0; 21:0; 22:0

which is profile 21 on HP 2335a.

On the host side, the printer name is foo. This means that when a user

types lp -d foo /tmp/file, the file /tmp/file will be printed on this

printer. The X.25 interface on the host is interface0.

Printer Configuration

To configure a printer (foo in the examples below) for use with the

standard UNIX LP spooler system and x29printd, follow these steps:

Step 1. Edit the /etc/x25/x29hosts file to include:

printer {

device x29printer1

name interface0

remote_x121 408555120305

x3 default_printer

logging 3

}

x29printd uses /etc/x25/x29hosts to configure remote PAD printers.

Step 2. Execute /usr/sbin/x29printd with the -l3 option.

After /usr/sbin/x29printd starts, it creates a device file named

/dev/x29/x29printer1. You can verify that this device file exists with

the command: ll /dev/x29.

x29printd creates the device file by linking it to a slave PTY. This

master/slave PTY pair is the interface for lpsched and x29printd (see

the pty(7) man pages for information about UNIX PTYs). The device file

for printer foo will be written to /dev/x29/x29printer1.
