Applications Using npd

Sun NeWSprint

Sun NeWSprint page accounting works with PostScript printers. It utilizes the bi-

directionality of the M204’s serial ports to get this status back to the host.

If the printer is attached to one of the parallel ports, no page information comes back

from the printer. This causes Sun NeWSprint to assume a communication problem

and disable the queue. To avoid this, remove the af= ﬁeld in the /etc/printcap entry

and set the HANDLER_INTERFACE variable to PARALLEL in the .param ﬁle

located in the printer’s spooling directory.

Add a new Sun NeWSprint printer entry with the add_np_printer program. The

pseudo-tty device is a serial interface. Therefore, when this program prompts you for a

device interface, select Serial and device sufﬁx a for any port on the unit.

After NeWSprint creates the necessary spooling directory and entry in the /etc/print-

cap ﬁle, set the lp= ﬁeld in the new entry to the devicefile argument of the npd pro-

gram.

The modiﬁed /etc/printcap entry looks like this for a PostScript printer named ps

attached to com2 on the M204 named spike:

# entry for a PostScript printer on a serial port
