I. WHY WOULD I USE HP JETPS.NLM
______________________________________________________
Hewlett-Packard's JetPS.NLM is a NetWare Loadable Module (NLM) that runs on
NetWare 3.x and 4.x file servers. This NLM provides the same NetWare printing
functionality as HP's Jet Direct products; it allows you to manage and
control a peripheral attached to a parallel port on a NetWare file server.
This product can be used as a replacement for Novell's PSERVER.NLM.
Like PServer, JetPS will service print queues on one or more file servers.
However, JetPS.NLM has added features, as Table 1, Product Comparison,
details.

JetPS.NLM has a built-in IEEE 1284 driver that it uses to communicate with
peripherals through a standard parallel port or any other IEEE 1284-compliant
port hardware. JetPS.NLM's IEEE 1284 driver is backward compatible with
existing peripherals that use the PC parallel interface (commonly referred
to as the Centronics interface) but will take advantage of the higher
performance and bi-directionality of an IEEE 1284-compliant peripheral's
interface.
************************
Requirements
************************
JetPS.NLM is compatible with the following 3.x and 4.x versions:
-- NetWare 3.11 and above
-- NetWare 4.02 and above
NOTE: This version of JetPS.NLM does not use NetWare Directory Services
(NDS). Instead, it uses Bindery Services.
Each time JetPS is loaded on a file server, it requires 500 Kbytes of RAM and
will use 500 Kbytes of small memory pool space.
************************
Installation
************************
To install JetPS.NLM, copy all of the NLM files from this distribution to the
SYSTEM directory of the file server where the NLM will run. The latest
version of JetPS.NLM can be obtained from one of the electronic services
listed in the "Software, Driver, and Flash Image Upgrades" section.
************************
Using JetPS.NLM
************************
You can load JetPS.NLM up to four times on a file server to service
peripherals on any combination of parallel ports--LPT1 through LPT4.
To load JetPS.NLM, from the NetWare system console prompt:
1. Type "LOAD JETPS <port number>"
For example, if you would like to run JetPS.NLM to service a printer attached
to LPT2, type "LOAD JETPS 2".
You can add this line to your autoexec file to automatically load JetPS.NLM
when the server boots.
************************
Trouble Shooting JetPS.NLM
************************
NetWare 3.xx servers sometimes run out of memory in the short term memory
pool. If JetPS.NLM will not load and NetWare displays one or both of the
following messages:
"Insufficient returnable memory to load NLM"
"Cache memory allocator out of available memory"
follow these steps to increase the amount of short term memory
allocations.
1. To find out how much memory the server is currently configured to
allocate to the short term memory pool, type:
"set maximum alloc short term memory"
2. Place the following statement into the startup.ncf file:
"set maximum alloc short term memory = <number>"
with <number> set to a value at least 500,000 larger than the
current short term memory pool size. For example:
"set maximum alloc short term memory = 3145728"
3. Restart the server.
______________________________________________________
II. CONFIGURING JETPS.NLM
______________________________________________________
You can configure JetPS.NLM to operate either as an RPrinter or a QServer.
Novell defines RPrinter as a remote printer interface. RPrinter is typically
run as a TSR on a NetWare client to make a client-attached printer available
to other users on the network. You can configure an RPrinter to connect to
Novell's PServer (either PServer.EXE or PServer.NLM). PServer pulls print
jobs from a NetWare queue and sends them to RPrinter, then RPrinter sends the
print job data to the printer. When operating as an RPrinter, JetPS.NLM will
connect to PServer and send print job data to the file server-attached
peripheral it is servicing.
HP defines QServer as a high-performance, remote printer interface. QServer
pulls print jobs directly from a NetWare queue and sends the print job data
to the peripheral. The Administrator can configure HP's QServer to service
up to 64 queues spread across as many as 16 file servers. For each remote
server it services queues from, HP's QServer, like PServer, uses a licensed
connection. As an NLM, JetPS.NLM does not use a licensed connection to the
server it is running on, even if it is servicing queues on that
server. To increase performance, HP recommends running in QServer mode.
______________________________________________________
III. CONFIGURING AND MANAGING YOUR NETWORK
PRINTER
______________________________________________________
In order to configure and manage your network printer, you will need to load
the HP JetAdmin software, the same software that HP provides for HP JetDirect
products. For both JetPS.NLM and JetDirect, HP JetAdmin provides the same
advanced control, status, and diagnostic services. As a result, when using
HP JetAdmin with JetPS.NLM for server-connected printers and
HP JetDirect for direct-connected network printers, you will have uniform
view and control of all of your network printers.
NOTE: For optimum performance, HP recommends that you set printer I/O
buffering to 100K.
To receive information about HP JetAdmin products and how to use them, see
the Software, Driver, and Flash Image Upgrades section at the end of this
readme file.

IV. WHY WOULD I USE HP JETDIRECT PRINT SERVER PRODUCTS?
______________________________________________________
HP JetPS.NLM is based on the Hewlett-Packard JetDirect print server
products. Both allow management and control of peripherals attached to
parallel ports using the HP JetAdmin software. However, unlike JetPS.NLM,
JetDirect print server products allow location flexibility by directly
connecting printers to the network users. Jet Direct products also increase
performance by eliminating parallel port bottlenecks. Finally, JetDirect
products support multiple protocols and networks, as illustrated in
Tables 2 and 3.
