After much patience trying different drivers on localhost:631, I finally found one that enabled me to consistently print two-sided documents (page 1 on the front, page 2 on the back) on my HP Laserjet printer, from both libreoffice writer and from okular.

So I thought I'd try scanning an image on my scanner. It is powered by the USB cable that connects it to the computer. First I tried gscan2pdf 1.5.1, which is linked to the KDE GUI at K-->Graphics-->Scan to PDF. It scanned, but nothing appeared. Twice. So I installed xsane 0.998 w/ APT. It recognized my scanner and appeared to scan when I pressed the application's scan button. However, the only graphics it displayed was a black rectangle 220 x 69 pixels. So it doesn't work either, not in the three times I tried.

There have been issues with Linux & Canon LIDE scanners for a while. In this thread I found a fix that worked for LIDE30 & LIDE50 scanners, perhaps it will help with yours as well.

Thanks, timkb4cq, for bringing that thread to my attention.
I tried the fix, rebooted, and rescanned w/ xsane a couple times. Now I consistently get a a black rectangle 220 x 69 pixels. Hmmmmm?

Code: Select all

root@mx1:/home/jon# grep USB_BLACKLIST /etc/default/tlp
#USB_BLACKLIST="1111:2222 3333:4444"
USB_BLACKLIST="04a9:220d"
USB_BLACKLIST_WWAN=1
root@mx1:/home/jon# lsusb | grep anon
Bus 003 Device 003: ID 04a9:220d Canon, Inc. CanoScan N670U/N676U/LiDE 20

I see there is a USB_BLACKLIST_WWAN variable too. Maybe I should see if I can find out what it does.
