not sure what I'm doing wrong

[jd1701d]

when I try to print something on my ld 002r most of the time it disconnects and gives me the error starting a print.

it's a real crapshoot to get something to print most of the time and then there's 2 connects in the port options which are named the same thing.
I don't really know where to start figuring out what's going on let alone fix it, I'm vary new at programing.
