HP Printer in Ubuntu 14.04

I’ve installed HP printers on a laptop prior… though by “install”, I mean that I plugged a printer in and it just worked. Ubuntu uses the open source HPLIP drivers.

This wasn’t the case for my home computer.

I was recently gifted a HP LaserJet P1005 and although it popped up in the printer list, I was unable to print to it. Ubuntu told me the print jobs were sent, but nothing comes out. Some online searching revealed the solution(s).

First, I found this article, which has a commandline sample that ensures my hp-setup command would work.

sudo apt-get install hplip-dbg hplip-gui

Apparently, this is related to a broken printer driver, which can be fixed with the following command.

sudo hp-setup

This install didn’t initially work for me, as I was receiving the following error.

… hplip-3.15.2-plugin.run file does not match its checksum. File may have been corrupted or altered.

To fix this, I followed these instructions and went to the HPLIP website and grabbed the two corresponding files (.run and .asc). Now, when running the hp-setup wizard, it asks if I want to download drivers or use local files.  Go with the local option and browse to the path of the files you just downloaded.

That was it.  Internet saves the day yet again.

These images might help you if you’re trying to get recording to work. The answers are out there, but this puts them together in a nice visual package.

Turn up the Mic AND Analog Mix!

CUDA Install for Linux (Ubuntu)

There’s some documentation out there for installing the CUDA SDK for Linux and it all seems to be good, though I did run into some little hitches when trying to run programs that take advantage of CUDA.

When running the 64 bit CUDA executable for 3D Coat V4, I received the error, “Error cannot load shared file libcudart.so.3 where is libcudart.so.3”. I found this information for correcting the error using an http://www.cyberciti.biz/faq/set-environment-variable-linux/.

This resulted in the following shell file that I dropped into my home folder.


export LD_LIBRARY_PATH=/usr/local/cuda/lib64
cd /opt/3D-CoatV4-0 && ./3d-coat-64-CUDA

Maybe now, combined with my recently purchased GTX 580, I will see some serious improvemnets in my voxel sculpting and simulations. For good measure, I can’t forget about all the inspiring sculpting work out there.
