I want to communicate with printer by using ruby language. i am using socket programming to communicate with printer. my printer ip is “192.168.24.687” and port number is “20000”.
Below is the code that i am using to communicate with printer
require 'socket' sock = TCPSocket.new('192.168.24.687', 20000) sock.write 'MARK START' sock.close
In the above code i am sending “MARK START” command to the printer which will turn printer ON , but it’s not working. with above code i am able to established connection with remote server but not able to send “MARK START” command.
But the same is working with putty. with putty i am using connection type as
"raw" and connecting to the printer.After connection is successful i can send command “MARK START” to putty and able to turn on printer.
I want to know why my code is not able to send “MARK START” command to printer??
