 Hello CUPS Help Mailing List People,
We are trying to run CUPS 1.7.5 on HP-UX Itanium and are having difficulty.  While the cupsd process does start and provide a web page, the lpstat command hangs from the user command line when used with certain options, but hangs with other options.  Below, I'll show what does work, and what does not, as well as cupsd.conf, printers.conf. 
Aside from lpstat not working, we are not able to print anything, with the exception of a printer self-test page, which cups is able to request.
Please advise best course of action.
Thank you,
Peter KloskyFairfax, Virginia, USA
Problem scenario log below.  User command was "lpstat -p", and the result is that cupsd accepts the connection, gets a request from the client, writes to the lpstat client, then hangs, waiting for a response from the client.  The client never responds.

Scenarios that work are shown below, first the commands, then the associated log.  The lpstat client creates EOF conditions, as expected.  This all seems correct.
# ./lpstat -r
scheduler is running
# ./lpstat -d
system default destination: kyocera
# ./lpstat -l
