Communicating with CP30 over Telnet

When attached to a network (either wired or via WiFi) you can communicate directly with the CP30 and issue ZPL commands by using terminal software for testing.

Before you begin you will need:
  • CP30 connected to your network (wired or via WiFi)
  • The network IP address of your CP30.
  • Terminal Software:  for Windows we recommend Putty, for OSX we recommend using telnet from the terminal.

Windows: Using Putty

We recommend using Putty, a free Telnet client.  Once downloaded and installed, follow the below instructions.

Open Putty.  You will need to enter the IP address of your CP30 printer into the Host Name (or IP address) box (#1).  Then set the Port to 9100 (#2).  Set the Connection Type to Other: Telnet (#3).  Finally click the Open (#4) button to connect.

Once connected, you should be able to send ZPL commands to your printer.  For example entering ~HI will display information about the printer.

OSX: Using telnet

  • Open terminal by hitting command+spacebar and entering terminal.app
  • Once presented with the terminal window run the command telnet
  • You need to set telnet to run in binary mode by entering the command: set binary
  • Open a connection to the CP30 by entering the following, replace 192.168.0.X with the appropriate IP address: open 192.168.0.X 9100 
  • You can now directly enter ZPL commands and send them to the CP30.  For example entering ~HI will display information about the printer.
  • To quit hit control+] and then type quit
