I suppose this should work ok if done when cupsd is not running. I'd be inclined to modify the existing queue or set up a new one. A virtual queue would allow testing Tea4CUPS without wrapping the backend. The printer is being powered on by some type of electronic switch? > /etc/cups/printers.conf: > DeviceURI tea4cups:/http://hpljwlan:631/ipp/ http:// is a symlink the ipp backend. It's always useful to know what model of printer is being used. > I configured the printer power on script: > > /etc/cups/tea4cups.conf: > > > but I get unfortunately an error in /var/log/cups/error_log > > > E [30/May/2018:08:51:40 +0200] [Job 16] Tea4CUPS (PID 9689) : Traceback (most > recent call > last): > > Is seems something goes wrong while setting the TEABILLING environement > variable. > > Has anybody an idea why that could be? tea4cups.conf is the configuration file for Tea4CUPS. I guess you are using a prehook or posthook to activate the printer; we really need to know what you have for it (including any associated script). What part does TEABILLING play in the process? -- Brian.
