Cups importing/exporting

[Dustin]

Kurt,

All of the 80 servers do use the same print que because all of them are administered here by me, so if a remote location in another state is having an issue I can administer it, or if there is something I am doing here and I want to print it off for someone, I can select the printer in their location print it off, and just call them and let them know its on the printer for them, saves on email time.  The script was something I created, but the variables such as the import and export were features provided by the cups website for version 1.1 and I have been unable to find any for version 1.2.  I am sure I could do it all in about 8-10 hours, but I dont want to do that if possible, cause like I said all 80 remote servers are administered by me so I have a lot on my place.:-)  I think I will just take a look into a bit more and if I cant find any other info I will just have to donate some of my schedule to doing this manually.  Thanks for the help

> Well, if you have ssh access (preferrably, "passwordless", using a key file) for root on all 80 servers, it is just a little bit of work to write a little set of small scripts that do the following:

>           for all printqueues; create a tar archive for them
>        -- (take separate care for cases where you have "raw" queues, or

>   (2) delete all current print queues on a server
>   (3) update to CUPS 1.2.11
>   (4) re-install the printqueues again, based on the info which was

> My guess is that you need about 1 day / 8 hours to create (and test!) the scripts, and 80 minutes to finally run the scripts via ssh, and another day to check if all servers and their queues are working as expected.

> If you leave away the "-nd" command to the wget command, you'll get nice local subdirectories structure for each remote server with the printernames/PPDs inside each (instead of all PPDs the flat current directory).
