i am a geek. i like expensive fragile useless toys, er, i mean tools.

I’m posting this in the hope that it will somehow greatly simplify somebody’s day. I did this the hard way, over and over, until I made it work for me; hopefully this all goes much easier for you!
The issue at hand is making the Brother QL-570 thermal label printer work as advertised on a system running Ubuntu Linux. This guide is written with the complete newbie in mind; skip over any bits that seem too obvious. The driver installation instructions provided on the Brother website can be daunting to a beginner, and contain a few subtle errors that may trip you up. I performed these steps in Ubuntu 10.04, but they should work in any version newer than 8.04. Ubuntu made a fine go of installing the required drivers all on its own, but I finally had to go through it the long way to get things working well.

First off, it’s a great help to have the nautilus-terminal application installed. Basically, it adds a command-line terminal window to the standard Nautilus file browser. This lets you navigate folders and do common tasks with the simple GUI interface, then seamlessly switch to the command line interface (already in the proper directory!) with a point and click. To install nautilus-terminal, open a standard terminal and enter the following lines, being sure to enter your administrative password when prompted:

  • sudo add-apt-repository ppa:flozz/flozz
  • sudo apt-get update && sudo apt-get install nautilus-terminal

Now restart nautilus by pressing ALT+F2 and entering:

  • nautilus -q

Re-open Nautilus and notice the terminal window at the top.

Now open a browser window and go to the Brother driver download page. For a typical Ubuntu install, you only need to download the .deb format drivers, in particular the LPR driver and the cupswrapper (inch) driver. While you won’t need it quite yet, you might as well grab the template file download while you’re here. Go ahead and download these (you’ll need to click through some licencing screens).

Create a new folder on your desktop, named something obvious like “Brother Drivers”. Open your Downloads folder, then drag the driver files over into the new folder you just created. This will make them simple and easy to open. Now open the new folder in Nautilus (which is the default file browser; just double-click the folder). Notice that the command-line has you already in the correct directory. Click into the terminal, and enter:

  • sudo gedit /var/lib/dpkg/info/ql570cupswrapperinch.list

This will open a text-editor. Copy the following text into the text editor window, then save and exit:


Nothing spectacular should happen here; you’ve just added a file that will prevent an error message from pestering you a few steps later. Now, back at the command line, double-check that you are still in the same directory/folder as the drivers: the two drivers and the tar.gz will be shown in the GUI portion of the window, and the command prompt in the terminal portion of the window should say “~/Desktop/Brother Drivers$”. At the command line, enter the following:

  • sudo aa-complain cupsd
  • sudo mkdir /usr/share/cups/ql570
  • sudo dpkg  -i  –force-all ql570lpr-1.0.0-1.i386.deb
  • sudo dpkg  -i  –force-all ql570cupswrapperinch-1.0.0-1.debian.i386.deb

You may have seen an error message flash past during that step. As long as nothing hangs on you, it is safe to ignore. Now, check that the drivers installed correctly. Close the file browser window, and open a straight terminal window. Enter the following:

  • sudo dpkg  -l  |  grep  Brother

You should get some confirmation of the two drivers. Now open a web browser and go to  http://localhost:631/printers to find the CUPS web-panel. Choose the QL-570 from the list. Under the Administative pull-down menu, select “Set Default Options”. Here, you may need to fiddle with the paper sizes to get best results. The recommended default for me was “62mmx4”, but this ended up printing 3 blank labels after every job. “62mmx100mm” Seems to be working well for me right now… After making any changes, return to the printer page and select “Print Test Page” from the Maintenance pull-down.

Those templates you downloaded earlier? Unzip the qt570l110.tar.gz to find a selection of template printing files for Open Office and others.

I couldn’t find much on the interwebs about overclocking Zotac’s Ion motherboards. This was especially true with systems running Ubuntu Linux. Since I couldn’t find many in-depth results of such experimentation, I’ve decided to post some of my own. This isn’t the most accurate or objective test, but maybe these results will help someone else with their own experimentations.

I started shopping for a new computer months ago. While I’d repaired and rebuilt a number of laptops and old desktops, this was to be my first completely-fresh, bottom-up build. During both the research and building phases, there were a number of questions I couldn’t (at first) find answers to. Hopefully, this post will provide an answer or two for somebody else out there trying to do something similar.

Today, this morning, I bought a 350Gb external hard drive at a yard sale for $6. The housing was badly cracked and the power cord was missing. The seller claimed that she didn’t know if it worked or not, but that she had no use for it in any event. I took it home, pulled it from the damaged case, found a compatible power supply from my geeky collection, hooked it to my computer, and had a surprise.

Not only did it work, but buried in the drive’s directory was a complete back-up of 5 year’s worth of detailed financial records: their investment club accounts, Ebay transactions, mortgage paperwork, rental agreements, E-Trade account back-ups, automobile sales transaction records, etc. In short, a complete assessment of their entire financial lives over at least the last five years; a brutal resource for any identity thief.

Of course, my own moral code prevents me from taking criminal advantage of this information. The real dilemma, for me, is how to proceed. Should I wipe the drive and never speak of it? Should I go back to the seller and return it? Should I let them know that I wiped the drive? Should I give them an opportunity to recover the information if it is still valuable to them?

Ignorance is bliss, but if some family member later recalls that there might have been a ridiculous breach of security in that innocent sale, perhaps some communication now might save their sanity later.  Further com pounding the dilemma is the fact that the seller is someone socially acquainted with my ladyfriend; we are not close friends, but neither are we complete strangers.

My ladyfriend seems to feel that communicating with them now might just add unnecessary stress and and worry to a situation that would be easily preempted by an otherwise silent and anonymous deletion of the drive.

What would you do?
