Gilles,

No, no, no.  You didn't read what I said carefully.  I said the
backslashes have to be escaped *twice*!  You missed the single quotes.
The correct syntax would be

$ lpr -P '\\\\mimosa\\glaieul' gettime.c

(note the quotes).  That's what worked for me, and should work for you as
well.  Alternatively,

$ lpr -P \\\\\\\\mimosa\\\\glaieul gettime.c

should also work.

That shouldn't matter.  The lpr you're using is smart enough not to care
too much.

That lpr comes from cygutils, but even the windows one should work in this
case.
