Hi, 
I don't know if you can follow that instructions or not. Obviously, you haven't to install a raspbian, because you do have installed one.

But I want to give you some advice, as I'm a Linux user (and I have been a beginner, and perhaps I am already...). Excuse me if it isn't necessary... 

Change the file /boot/cmdline.txt with your favorite text editor (remember to sudo edit because its a normally locked file). You need to remove references to the /dev/ttyAMA0 device. For me, this changed from

Before you make some changes in such a configuration file, I recommend you to make a copy of that file in a term:

Code:

sudo cp /path/file /path/file.backup

In the example, sudo cp /boot/cmdline.txt /boot/cmdline.txt.backup 
(cp is a console command to copy a file or directory)

If after edition you have some problem, you can restore the original file with this command, for example:

Code:

sudo cp /boot/cmdline.txt.backup /boot/cmdline.txt

Good luck

Can I utilize /dev/tty/AMA0 for the printer or I will compromise some openplotter features?
