Hi,
I believe the problem is actually that your printer does not accept plain
text input. You need to run it through a filter first. The problem is that
many new printers only accept input in the form of a binary command
language. In the case of this printer it is through GDI, a windows
standard.
I notice on the Brother website that a linux driver is available. Perhaps
this would be a starting point.
It would definitely be worth checking out CUPS, the Common UNIX Printing
System. I don't know if it supports this particular printer but it
seems to
offer support for a lot of different printing devices.
Hope this helps,
Duane Whitty,
