Brother HL-2070N on Linux

From: "andrew cooke" <andrew@...>

Date: Fri, 3 Aug 2007 21:54:27 -0400 (CLT)

We just bought a laser printer - Brother HL-2070N.  It's fairly compact,
nice looking, monochrome, network printer and it was very easy to
configure for both Linux (Suse) and Mac (OS X).

I connected it via ethernet, turned it on, and it requested an address via
DHCP.  I checked what address was assigned and pointed a browser at the
address - it contains a web server that lets you do all the configuration.

So I gave it a fixed IP address (not sure this was necessary - the Mac at
least can use rendezvous) (and then changed the browser to the new
address!).

Brother has rpms available on its web site.  You need both the standard
lpr and the "CUPS wrapper" (cupswrapperHL2070N-2.0.1-1.i386.rpm 
brhl2070nlpr-2.0.1-1.i386.rpm).  I downloaded those and installed them
with rpm --install.  At that point I saw a strange error about pstops not
found so I used Yast to install psutils.

Then I pointed my web browser at http://localhost:631 and the printer was
there, registered.  The Brother site mentioned copying a file for AMD64
but it wasn't necessary - it just worked.

By default the config is for USB.  I changed the settings via CUPS to be
at the address I had configure earlier (ie http://10.2.0.4/ipp - the ipp I
took from the examples on the CUPS page).

A test page printed fine (and the toner save mode looks plenty good enough
so I enabled that).

On the Mac we installed a driver from the provided CD and then added a
printer through the normal admin interface.  It did some kind of
autodiscovery and worked fine too.

The only downside is that the supplied toner is a "Starter Cartridge" with
about half the capacity of a normal cartridge.  It didn't say that
anywhere on the box, or on the website from the shop we bought it from.

Problems with OSX (Apple Mac)

From: "andrew cooke" <andrew@...>

Date: Thu, 1 Jan 2009 22:42:00 -0300 (CLST)

Printing from the latest OSX, the printer would not respond (it stayed
asleep, with some poking CUPS could be provoked into giving an
uninformative error).  A comment on Amazon suggested a DNS lookup issue,
but that seemed to be windows-related, and the problem persisted even when
I supplied a name via DNS.

I eventually solved the problem by configuring the printer (when first
added) to use the LPD daemon rather than CUPS.
