I have been searching and searching for the HP JetDirect Network Interface Configuration Guide. I need some information from this manual any help would be greatly appreciated.

[Marco A.]

What exactly you need about it?, I have another similar book, maybe could help you ..., I'm sending it attached to this message.

Best regards,

Marco

A lot of documents make reference to this one, but apparently this is not in pdf format for distribution.

New guides have a lot of that info, what's the problem that you are having with that?...

Best rgds,

I am basically trying to get more information on how the JetDirect configuration works within SAM, (ie how it differs from HPPI. Does it kill all print jobs in the que like HPPI or retains them.) I work in a live enviroment, so stopping the ques during business hours is not really an option.

[A. Clay Stephenson]

This is not a JetDirect question then. It is actually an lp question. The answer is independent of the type of printer: network, remote, or local. Because of the design of the lpsched daemon; the scheduler must be stopped to add or remove a printer.

[Gail Engle]

I was stating that as an example of what I am trying to find information on. I have seen references to the above mentioned document in several locations. With the referenced manual and the SAM manual I am trying to streamline some of the manual work being done.

OK. You really don't need the Guide you mentioned. All you really need is "man lpadmin" -- which will add and remove all local and remote (ie those using the LPD/LPR protocol) and man hppi, addqueue, and removequeue. If you wish to interactively add or remove a network printer (ie those which use the HP JetDirect port 910x protocol) then you use hppi. To add them from the shell, addqueue is used and to remove them, removequeue is used. SAM really just gets in the way of printer administration.

Easy answer: SAM does not do anything with network printers - it simply calls the hppi script.

hppi is just a simple script to connect the printer to the lp subsystem. The SysV spooler dictates the rules: add, delete or modify a printer and the entire spooling system must be shutdown. All jobs in progress will be halted and restarted when the spooler is restarted. This has been the case for decades and affects all printers, whether direct attached, remote print servers or JetDirect.

Almost all of us work in a production environment so this 'feature' of the SysV spooler is well known but must be worked around. Basically, you change the spooler at night or use an at job to schedule the change during off hours.

If this won't work, you need to replace the spooling system with a commercial (or freeware) spooling system. Note this is not a task for an afternoon. You'll need to evaluate the new system in terms of scalability, ease of use, tech support, compatibility, etc.
