UNIX systems. To setup LPD, first the async port(s) must be
configured to accept data flows without the chance of an EXEC session
starting. This is done using the command. The port should
transport all input and output types. The
commands sets the line to act as a permanent data pipe so the printer
data will be received by the printer without mistakenly being
interpreted as line control data. Serial line printers usually like
hardware flow control, whereas laser printers prefer software flow
control. Check with your printer's documentation for the preferred
setting.
To set up LPR service on lines 40 and 41:
Concord-GW(config)#line 40 41
Concord-GW(config-line)#no exec
Concord-GW(config-line)#no vacant-message
Concord-GW(config-line)#transport input all
Concord-GW(config-line)#telnet transparent
Concord-GW(config-line)#stopbits 1
Concord-GW(config-line)#flowcontrol hardware
Concord-GW(config-line)#exit
After the line(s) are configured, the command is used to define the LPD printer name. The
option fixes problems with single character line
terminators, which are not handled correctly by all UNIX systems:
Concord-GW(config)#printer cpop line 40 newline-convert
Concord-GW(config)#printer ccrunch line 41 newline-convert
After the router is configured, the UNIX or NT system that wants to
use the printer will have to be configured. Here are some sample UNIX
/etc/Printcap settings from cashbox.widgetco.com:
