I have never tried this but I believe it should work. You have to know
how to talk to your printer, usualy using some language like Postscript
or PCL or some vendor special language for modern ink printers.

I think that the old reports were from older FreeBSD version which
didn't have ACPI or from old machines which didn't have lpt in ACPI.
Nowadays "on acpi0" is pretty common.
