I have an Allen-Bradley 1769-L33ERM and I am trying to interface it with a Markem Printer Using the NGPCL Protocol over Ethernet and have not gotten any real results.
I have been all over PLCS.net and Google and I cannot get these to work. I have the NGPCL Manual from Markem and the Ethernet I/P Socket Interface manual from Rockwell.
I was able to create a socket, open a connection, and write without errors, but the setting I tried to change in the printer shows no change.
I tried a read from the printer also but where do I tell it what info I want back and where does the read write the actual information back to?
