I remember this from the recent past but don't see this message now, in either the FreeBSD ports version or NetBSD pkgsrc version.

For FreeBSD, I made a directory /boot/modules-toxic and moved the ulpt stuff there.

FreeBSD still couldn't find the printer.  Neither could NetBSD with ulpt commented out in kernel config.

FreeBSD and NetBSD printing setup couldn't find the printer even when I gave the USB address.

Now I intend to try again, using ulpt, for both FreeBSD and NetBSD.

I finally got the printer to print, early June 13, 2015, from NetBSD using Ethernet connection, and a newer .ppd file not yet in pkgsrc.

NetBSD couldn't find the printer normally but saw it when I gave the IP address.

I think that might work with FreeBSD too, but haven't tested it yet.

My printer is HP LaserJet Professional M1212nf MFP.
