RE: usd/lpd bind

[Hennessey, Mark F.]

I have a critcal issue with usd and lpd binding (stalling/hanging at the same time), 
the cause is unknown.

lpd is hung and displays as if the queue jobs were printing normally and the usa 
displays the first queued as;
Job # Job description  User namePri Forms   Size  Cps Status  Delay
006779 UniVerse ograma:38226  1996   1 1000%006783  
/snip

I used to get some similarly strange behavior (uv - Solaris lp queues).  I took the 
shot gun fix approach:
1) In UV Spooler/Device management I:
   a) created a lock file for each device /tmp/uvprintername
   b) instead of using /dev/null as the device for each UV printer,
  I created links in dev for each device pointing to the same pseudo device
  that /dev/null points to - so printer Jupiter would be configured in UV for
  DEVICE: /dev/Jupiter
  Lock1:  /tmp/lock.Jupiter

After making the above changes I still ocasionally get a barf condition, but it 
clears it self after a usa -o -p name followed by a usa +o...

Also of note:
2) Found that (at least on older versions of Solaris) lpsched would die and jobs
   would simply vanish, so I added the following to the print driver script:
# Test to see if spooler is running  
# Restart lp service if lpstat -r shows it's not running 
while [ ! -z `lpstat -r | grep not ` ] 
  do  
/etc/init.d/lp start
sleep 30
  done 
3) I give my unix printers the same name as my uv printers, so one script service 95%+ 
   of my printers...
4) Since the printing script is run by root you may want to make sure the permissions
   are set to -rwx-r-xr-x, or even tighter.

RE: Brower based terminal emulator

[Hennessey, Mark F.]

snip
I can't find the info just now, but I have seen a java implementation of a terminal 
emulator that runs in a browser.  It should pop up in Google rather readily.

I think BlueZone from http://www.seagullsoftware.com/products/bluezone_terminal.html 
would fit the bill for PCs.  I'm not sure if they can support Linux or real *nix 
though.

RE: UV losing print characters

[Hennessey, Mark F.]

snip
a client has reported that they are randomly  infrequently having
characters dropped from print jobs.
/snip

How does the job get from the UV server to the printer?

Are they on Windows or Unix?  If Unix, are they using a 'driver' to pass the data from 
UV's spooler to lp?

Use the wIntegrate execute command on pc function to display the file.

We do something similar using rsh (wrshdnt runs on each pc)...  I think the pc command 
you'd want (assumine internet explorer in a default instal):
/progra~1/intern~1/iexplore {url to where the jpg is located} 

We pass a url that leads to a small *nix machine running apache that mounts a 
directory from our production machine.  Just like that, our old character based 
application reaches out, opens IE and sends the user to the exact pdf they want...
