Setting Up and Servicing Print Servers

Using the PSERVER Daemon

The NetWare Services print server is implemented as a UNIX daemon called

PSERVER. It runs as a UNIX process and can only be started at the NetWare

Services server. You can use the console command pserver to start the

daemon. Only one PSERVER daemon can be running at any given time on a

NetWare 4.1/9000 machine and it must be started by a user with root

privileges.

Services Provided by the PSERVER Daemon

The PSERVER daemon provided with NetWare Services has all of the

components necessary to service print jobs in NetWare and HP-UX

environments. The components needed to accomplish this are built into the

PSERVER daemon so no additional drivers or components need to be added

for compatibility.

In the NetWare environment, the PSERVER daemon communicates with

NetWare printers using the NPRINTER port drivers (NPRINTER.EXE on a

DOS, Windows, Win 95 or NT workstation, NPRINTER.NLM on a native

NetWare server,). NetWare Services provides NPRINTER.EXE and the

NPRINTER daemon.

Printers using NPRINTER software should be conﬁgured as Parallel, Serial,

or Other/Unknown using PCONSOLE, or NetWare Administrator. The

communication between the PSERVER daemon and a remote NPRINTER

process will use the standard NetWare protocols (IPX/SPX).

In a UNIX environment, the PSERVER daemon communicates with remote

UNIX print systems using the line printer daemon (lpd) protocol. This

communication occurs using BSD sockets over the TCP/IP protocol.

Remote UNIX print systems should have an lpd conﬁgured or an emulation

package that can accept print requests using this protocol. Print job status is

also updated by communicating with the remote print system using this

same protocol. Printers using this protocol should be conﬁgured as “UNIX

Printer” type using PCONSOLE, or NetWare Administrator.
