Hello,
The setup is:
- 1 HP LJ printer with JetDirect - 2 lprng queues both printing to port 9100 of JD
My question is: does lprng SW some kind of destination device locking? (so sending job to both queues at the *same* moment will not result at two lpd daemons to try to send job to a port 9100 at once?
|----------| |----------| | Queue 1 | | Queue 2 | |----------| |----------| |_________________| | \|/ |----------------------------| | HP printer on JD port 9100 | |----------------------------|
Thanks for any answer,

Thanks for answers,
haven't chance to test it yet. I'll try "ss/sv way" and "lpd_bounce + lp:[EMAIL PROTECTED]" as well.

This is text I found in "The Printing cookbook"
Chapter 8. Wildcards, Bounce Queues, and Forwarding
One of the things you might want to do is have a set of queues that massage the various jobs and then send them to a destination printer.
Figure 8-1. Evil (BAD) Way
landscape:force_localhost
:ifhp=model=xx
:filter=/.../convert_to_landscape | /.../ifhp
:lp=10.0.0.14%9100 portrait:force_localhost
:ifhp=model=xx
:filter=/.../convert_to_landscape | /.../ifhp
:lp=10.0.0.14%9100 lp:tc=.common
:ifhp=model=xx
:filter=/.../ifhp
:lp=10.0.0.14%9100Each queue will now fight for a connection to the destination printer.
8.1. Bounce Queues
Figure 8-2. Not So Evil Way
landscape:tc=.common
:filter=/.../convert_to_landscape
:[EMAIL PROTECTED] portrait:tc=.common
:filter=/.../convert_to_landscape
:[EMAIL PROTECTED] lp:tc=.common
:ifhp=model=xx
:filter=/.../ifhp
:lp=10.0.0.14%9100You have various filters set up so that each queue does a conversion and then forwards it to the real printer for output. No fighting. This method is called bounce queues as the job bounces through the queues, getting modified at each stage.
