SolutionNow here's why this is very confusing:
In the old days, print servers were Unix boxes and PCs running WinNT with the Unix printer sharing services enabled (RFC 1179). So with lpadmin (or SAM), you would configure a printer as a "remote" printer. But in the last few years, many non-HP printer manufacturers have built LAN cards and adapters that use the lpr/lpd protocol found in RFC 1179 and while they are LAN-based printers, they do not use HP's proprietary JetDirect protocol. These print servers must be added with lpadmin (or SAM as remote printers). Note that remote printers are very crude -- no lp -o options will work.
For HP printers using HP JetDirect LAN cards, you would use the hppi (which SAM will run for you when adding a "network" printer), or use the command line interface to hppi tools: addqueue
For HP-UX, the worst connections for printing are remote printers. Remote print servers (whether computer-based or part of a LAN card) cannot process lp -o options so print jobs from HP-UX must be pre-processed before printing. The JetDirect protocol uses port 9100 and a special spooler-to-LAN program called hpnpf to allow a huge number of options to be processed. See man net_ljx000

Re: Addqueue VS lpadmin
lpadmin = classic spooler addqueue is networking addon
addqueue allows a user to build an lp printer queue based on arguments entered on the UNIX command line, and provides a non-GUI alternative to the method provided by the hppi Utility.
It is not to be used to create a queue for a printer connected directly to a LPT port.
Addqueue is the only correct tool for network printers
hppi -addq is another way

Re: Addqueue VS lpadmin
note that hppi and friends create entries in the lp printer base, so lpstat (and friends) will see/list/... these printers just like all other printers, which were created by lpadmin.

Re: Addqueue VS lpadmin
Thanks for the valuable reply.
i was worried about when we add the printer through lpadmin , it is going to recycle the spooler and there is a chnace of loosing some print jobs which is already is Queue. and addqueue command also recycling the spooler.
is there any way to add or change the configuration of the printer without distrubing the print spooler..
