Subject: Re: CUPS Interface Script

lee

i have messed with the server script before and to grab and keep errors, this is what i placed at the beginning of the script:

LogLevel debug2
LogDebugHistory 500
MaxLogSize 1m
MaxClientsPerHost 10
Listen localhost:631

the attributes must have proper case as per the cups docs: 
  web address is: http://localhost:631/

look at /var/logs/cups/error_log

and look for the line: Loaded configuration file "/etc/cups/cupsd.conf"

look for any errors after that. i found that several attributes were no longer used so i removed them.

let us know how u solved it.

I am trying to set up a CUPS printer that will print a single print job on two separate printers.  I saw a technique online using a CUPS interface script, but it seems the interface script is being bypassed (the first line in the script uses echo to put some text into a file in my home directory, which is not happening).  The method is to create a printer with the URI set to /dev/null and an interface that spawns two new print jobs, one to each of the two printers you want it to print on.  Here is what I have done:

 

Script interface_script:

#!/bin/bash

echo "Interface script is running." >>/home/me/debug

lp -d printer1 $6

lp -d printer2 $6

_________________________________

Create Printer:  lpadmin -p twoprint -i interface_script -v /dev/null -E

 

The lpadmin copies the interface_script into /etc/cups/interfaces/twoprint as expected and the permissions on the twoprint script are 755.  The CUPS LogLevel is set to debug2 and I don't see anything that looks to me to be an obvious problem in /var/log/cups/error_log.


I had this working in the past, but now I am trying to set it up again and can't get it to work.  Does anyone have an idea why the interface script is not getting run?
