Raspberry Pi Working as AirPrint Server

8 Replies

As I just posted on Twitter, I have successfully gotten my Raspberry Pi to function as an AirPrint Server for ios devices. This allows any of the ios devices connected to my WiFi network to print to my network printers which do not support native AirPrint functionality. It was a bit convoluted to set up and did require a heavy usage of the terminal but in the end it was totally worth it! It took me about 35 minutes to setup (including the 2 minutes I spent wondering why the iPhone couldn’t find the printer before I realized the WiFi was off)!

A tutorial (with step by step instructions) and a video demonstration will be coming out on Saturday, so stay tuned!

“Americanizing” the Raspberry Pi

19 Replies

The Raspberry Pi is made by the Raspberry Pi Foundation, a UK charity organization. For this reason the Debian SD card image (and presumably the others) default to the English – UK locale, timezone, and keyboard layout. For those of us in America, this is clearly not going to work! Clayton Smith excellently documents the procedure for Canadian’s in this post on his blog. I followed his procedure, replacing en_CA with en_US. To make it a little easier to follow, I have turned this into a photo-tutorial using PuTTY to remotely SSH into the device from my Windows 7 running Desktop PC.

First up is logging in, which uses the username pi and password raspberry.

Next, change the system locale from en_GB.UTF-8; to en_US.UTF-8 by running the command sudo dpkg-reconfigure locales.

Use the arrow keys to move up/down and highlight options. Use the spacebar to select/deselect the options.

Press tab to select <Ok> and then press enter.

Confirm your selection.

The Raspberry Pi will now generate the selected locales.

Now, it’s time to set the keyboard layout. Run the command sudo dpkg-reconfigure keyboard-configuration.

Next, we need to set the timezone. Run the command sudo dpkg-reconfigure tzdata.

Use the up/down arrows to select the appropriate location and press enter.

Use the up/down arrows (again) to select the appropriate timezone (closest city in your timezone) and press enter.

The Raspberry Pi will acknowledge the timezone change.

Next up is to modify the Debian packages source to use the US mirror (rather than the British one). Run the command sudo vi /etc/apt/sources.list.

Change the uk to match your two digit country code (us for me).

Write the changes to disk by pressing escape and then entering :w and pressing enter.

vi (the text editor) will confirm that the changes were written to the disk.

Quit vi (the text editor) by entering :q and pressing enter.

Then, run sudo apt-get update to update the package lists with the new source.

Finally, run sudo reboot to reboot the Raspberry Pi and confirm your changes.

Congratulations, your Raspberry Pi has been “Americanized!”

Raspberry Pi – It’s Finally Here!

I first heard about the Raspberry Pi last September and was immediately excited thinking about the endless possibilities of such a device. It truly could serve as the center of many things including a small linux server, a security camera to IP Camera converter, a small television mounted media center, and even the brains behind a small robot. At a price of $25 for the Model A version and $35 for the Model B version, it certainly is much more affordable than other such boards with this level of hardware. Both variants have a Broadcom BCM2835 – Arm11 CPU running at 700 Mhz with 256 MB of RAM and a Videocore 4 GPU. The only differences between them is the inbuilt USB hub and Ethernet ports providing two USB ports and 1 Ethernet jack directly on the board (Model B). This makes the Raspberry Pi a tremendous deal at $35 (for Model B).

After several manufacturing delays, the Raspberry Pi finally went on sale on February 29th with 10,000 available to buy. At this time, it was announced that the Raspberry Pi Foundation would not be the ones selling the Raspberry Pi (as was previously announced). To ramp up production quickly, Premiere Farnell and RS Electronics would be producing, selling and distributing Raspberry Pi’s. The first 10,000 were ordered by the Foundation and would be distributed to Element14 (Premiere Farnell) and RS Electronics when they arrived. I placed my order at Newark within minutes of the announcement, as the web-servers running the respective websites of Element14 and RS Electronics crashed. I was hopeful that I might have gotten one of the first 10,000 but cautiously so. At the end of the day, it was estimated that more than 100,000 Raspberry Pi’s were preordered.

It is now clear that there are in fact more than 350,000 preorders placed for the Raspberry Pi at this time. On Monday, I received an email from Newark stating that my Raspberry Pi had been shipped and I was ecstatic to hear that I had in fact, managed to get one of the first 10,000. After obsessively checking UPS for several days, my Raspberry Pi arrived on Thursday to my utmost delight!

After unpacking the Raspberry Pi, I burned the Debian release to my 8GB SD card and connected it all up and was greeted with… nothing. I had forgotten to actually put in the SD card (oops)! After putting in the SD card, the Raspberry Pi booted up with a proper terminal.

Next step: “Americanizing” the Raspberry Pi.
