How to Adjust the Printer Port Characteristics

1. Log in as superuser, lp, or assume an equivalent role on the print server.

2. Adjust the printer port characteristics.

   # lpadmin -p printer-name -o "stty=options"

   -p

   Specifies the name of the printer for which you are adjusting the port characteristics.

   -o “stty=options”

   Sets the port characteristic (stty option) specified by options. You can change more than one stty option setting with this command. Enclose each option in single quotation marks, and use a space to separate the options. For a complete list of options, see thestty(1) man page. Table 7–1 shows the default stty settings used by the LP print service.

3. Verify that the printer port characteristics have been changed.

   # lpstat -p printer-name -l
