Subject:  [VOICENWS] SW: Streaming LPR Port Driver for OS/2

From: "Bencivenga, Robert L." <r.bencivDESPAM at radium.ncsc.mil> 



IBM has released a new LPR driver for OS/2 at the Device Driver Pak for
OS/2. You will need Software Choice to access it though. 

This is the link (watch the line wrap):

The following is a listing for it.

                    Overview
 
 Streaming Line PRinter (SLPR) is a streaming port driver (SLPR.PDR) used
to connect your computer to a printer or print server via a TCP/IP
connection. The driver uses Line Printer Daemon (LPD) protocol as
specified in RFC 1179. This protocol is an almost universal way to send
print data to printers and servers. It is meant to be used as a
alternative to the \PIPE\LPD0 (henceforth LPD0) port driver which is
shipped with OS/2. 

                    Features
 
                    - Faster Thruput: 
                         Data can be sent to the printer almost as soon as
it is generated as compared to the LPD0 driver
                         which needs to wait until all the printer job is
generated before it is sent. 
                    - Simpler Setup: 
                         The LPD0 driver requires a separate program
(LPD.EXE) be up and running before it will work. Since
                         the LPD program is communicating with the printer
directly it has the status - not the spooler. 
                    - Better Error Handling: 
                         With LPD0 any problems are reported via LPD
program and not the spooler. With SLPR there is a
                         direct interaction with the spooler so error
recovery is more intelligent. 
                    - User Specified Time-outs: 
                         With LPD the default is to wait indefinitely so
out of paper or printer jams are not noticed for a long time.
                         With SLPR any waits longer than the user
specified time-out generates an easy to see pop-up
                         notification. 
                    - More Ports: 
                         SLPR can have up to 64.
