I managed to do the same typo twice. Model is MFC L2710DN. So, the `DN'
part was always correct; I erroneously replaced `1' with `5'.
In fact, the formats found by Johnny Billquist, `PCL6, BR-Script3 and
PDF' are supported by models `DCP-L2550DN/MFC-L2730DW/MFC-L2750DW', but
not by my printer.

It is no more important, but no, I think it's the WiFi interface
(present in DW, absent in DN).

Thanks for this! I paste the relevant part of the output (WARNING: paste
is several lines long):

I used this exact configuration (without modifying the
/usr/libexec/lpr/pjlfilter). Only blank pages were generated by the
printer.

I really would not be able to know if my printer has a specific name for
this queue (unless another telnet "conversation" can reveal it).

In fact CUPS is the possible solution, if no other one is available, for
me too.
Thanks for your help!
