Sort of, by omission.

At 10 seconds in, we have

[   10.744514] usblp 1-1:1.0: usblp0: USB Bidirectional printer dev 3 if 
0 alt 1 proto 2 vid 0x03F0 pid 0x1817
[   10.744529] usbcore: registered new interface driver usblp

then, at 12 seconds

[   12.582770] systemd[1]: Enqueued job printer.target/start as 175

Now if the kernel were "losing" the printer every 5  seconds, I'd expect 
to see some indication of it around 15 seconds, but nothing. In fact,

[   28.874663] device-mapper: multipath: version 1.4.0 loaded
[   29.076321] systemd[1]: Forked /usr/sbin/cupsd as 9332
[   29.076402] systemd[1]: Job cups.service/start finished, result=done
[   29.076550] systemd[1]: printer.target changed dead -> active
[   29.076555] systemd[1]: Job printer.target/start finished, result=done

and then suddenly

and so it goes, at 5-second intervals.
