HP 6122 (USB) powers on, but not off?

Asked by Ralf Hildebrandt

I have a HP 6122 connected via USB. Whenever I print something using
CUPS, it powers on automagically. But it doesn't power off! How can I
make it power down after e.g. 5 minutes idle time?

Sorry HPLIP does not provide the functionality of powering off the printers. We do power them on, however powering off is handled by the printer firmware. I've checked the DeskJet 6122 manuals and I haven't seen any references to any built in powering off system, so the printer may not support this.

You may have a difference experience with windows because the windows driver supports some functionality that our driver does not support.

I apologize for any inconvenience.

Thanks Aaron,

can you add this as a wishlist item for the HPLIP driver then?
I mean, now it's all about saving the environment...
