I wanted to recommend this to you, too, but I was hesitating because 
your printer could be too old. If you have a not-too-old printer, which 
does driverless printing on the network, it does in most cases also 
driverless printing via IPP-over-USB. And this does not only include 
driverless (IPP) printing, but also driverless (eSCL) scanning (if your 
device has a scanner built in) and the web admin interface, which would 
probably allow you to adjust the energy saving timeout.

Yes.

You should try. It is as easy as installing the ipp-usb package and once 
having it installed you connect your printer via USB and will see its 
web admin interface under

http://localhost:60000/

or

https://localhost:60000/

Note that with ipp-usb up and running you cannot use the classic driver 
anny more, but have to use the printer in its driverless mode. You will 
have to remove your current print queue and in a printer setup tool 
(like "Printers" in GNOME Control Center, system-config-printer, CUPS' 
http://localhost:631/ ...) look for your ptinter under the discovered 
network printers.
