Hi, i notice that with 12.1 (KDE) my Brother HL2240D doesn’t wake up if
i boot up the computer. Most of the time i need to turn the printer off
and then on.
With 11.4 this problem was not there, at least i never noticed it.
My question is, how can i check what the printer is doing or what the
usb port is doing and perhaps determain if its a bug.

Is the ‘sleeping’ printer detected? (I suspect not, but I don’t think that is the result of a fault or a bug).
lsusb
Is re-plugging the USB cable enough to get it detected, or does it need power-cycling to wake up?
I’m still using openSUSE 11.4, but if I get time I will test the behaviour with my Brother DCP-7055 printer.

I did not even try that. I just turned it off. After switching on it was ok.
Under 11.4 it was perfect. Just with 12.1 i experience this phenomena.
Strange.
The next time it happens i will use the command and see whats in it.
Right now everything is fine. I’ll keep posting.

Today the same happend. lsusb did show the printer but this time i
unplugged the usb cable and after i plugged it in it worked.
I wonder if there is another command that can show the status of the
printer. (like sleep or zombie).

I managed to find time to experiment with my printer in ‘deep sleep’ mode. I was able to wake my printer up (by sending scan or print jobs), even after rebooting with the printer left sleeping. If I ‘modprobe -r usblp’, I then could not contact the printer (as expected). Try examining whether the usblp driver is loaded on your system the next time this happens with your printer, using the ‘lsmod’ command. If it is not present, then try ‘modprobe usblp’, and sending print job.

Ok, i will do that. We will see why it happens maybe.

I tried all the suggestions but i did not wake up the printer. usblp was
there though.
The only thing that awakes the printer is unplug the cable or turn the
printer off.
