Ok, this is important to know. So it is a software bug, some software is telling the printer to power up.
Yes, that is what I think as well.
If without a driver it doesn't power up, it is not the printer sensing that the cable (USB?) is connected to a running computer.
I don't exactly understand that comment as written, so I will try to paraphrase it. "If there is no driver installed, and it still powers up, it must be a software glitch in 42.2 that is telling the printer to power up, rather than something in the printer itself sensing that the usb cable is connected to the computer and powering itself up."
Er... Yes. Let me try again: * It doesn't power up on other operating systems, only in 42.2 --> it is not the printer detecting power in the USB cable. * It doesn't power up before installing the driver --> it is a problem in the driver * It powers up before installing the driver --> there is some other software that tells the printer to power up.
I hope that makes it clearer for everyone to understand, and that is how I see it as well. I do think it may be in the HP software rather than specifically 42.2, as this behavior didn't start until I installed the printer and driver in yast.
Some HP printers can be installed without hplip. Mine can. Your printer, can be connected via network instead of USB cable? Mine works better via network than USB. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
