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.

papstatus

PAPSTATUS(8)							   Netatalk 2.2 						      PAPSTATUS(8)

NAME

       papstatus - get the status of an AppleTalk-connected printer

SYNOPSIS

       /usr/sbin/papstatus [-d] [-p printer] [retrytime]

DESCRIPTION

       papstatus is used to obtain the current status message from an AppleTalk connected printer. It uses the Printer Access Protocol (PAP) to
       obtain the status information.

       If no printer is specified on the command line, papstatus looks for a file called .paprc in the current directory and reads it to obtain
       the name of a printer. The .paprc file should contain a single line of the form object:type@zone where each of object, :type, and @zone are
       optional.  type and zone must be proceeded by `:' and `@' respectively. Blank lines and lines the begin with a `#' are ignored.	type and
       zone default to LaserWriter and the zone of the local host, respectively.

OPTIONS

       -d
	   Turns on a debugging mode that prints some extra information to standard error.

       -p printer
	   Get status from printer (do not consult any .paprc files to find a printer name). The syntax for printer is the same as discussed above
	   for the .paprc file.

       retrytime
	   Normally, papstatus only gets the status from the printer once. If retrytime is specified, the status is obtained repeatedly, with a
	   sleep of retrytime seconds between inquiring the printer.

FILES

       .paprc
	   file that contains printer name

SEE ALSO

       nbp(1), pap(1)
