Accessing printer through serial port
Hey, im new to processing so any help you could give me would be much appreciated.
I am trying to get control of the rollers on my 9 pin dot matrix printer (epson LX 300+). Initially I was going to do this through arduino but hope to do it through processing using the serialwrite programme.

The printer has a serial port and I am using the a serial to USB on my MAC OSX 10.4 system.

I am trying to understand the serial write application but am finding it very difficult.
In string portName = serial.list()[0] I'm not sure what to put in, but the result I get from doing this is:

Native lib Version = RXTX-2.1-7
Java lib Version = RXTX-2.1-7

but when I change the [0] to 1 I get:

Experimental: JNI_OnLoad called.
I googled these results and did not find anything too helpful.

I have been told that I should find the manual for the printer and this will tell me what to put into the simpleWrite, but what am I exactly looking for in the manual.

Any help you could give would be much appreciated.

Thank you.

p.s. I dont have a driver for the cable but can obtain it. Unfortunately I can't find drivers for the printer that will work on my MAC OS.
