I see you had your phone plugged in at the time the printer was not
seen.  Have you checked that is just coincidence?

If sometimes the printer is seen in lsusb and sometimes not then it is
likely an intermittent hardware problem.  The fact that it sometimes
works and sometimes not even when it is seen is also suggestive of
hardware.

I suggest you run
tail -f /var/log/syslog
which will show you that file and will show new stuff as it happens.
Then plug the printer usb in.  You should see it being recognised.
Unplug it and it should show it removed.  Plug it in again.  Try
wiggling the lead at each end, see if it comes and goes.  If you see
any problem try it in a different usb port.  I don't know whether you
have said, but if you are plugging it into a hub then try plugging it
in direct.
