- Unzip the zip file.
- Rename the unzipped folder to “pos_print_server”.
- Move the pos_print_server to document root (which is htdocs in XAMPP).
- Open Command Prompt or also called terminal. And go to the “pos_print_server” directory. You can go to this directory using “CD” command in the command prompt.
- From the Command Prompt which is now inside pos_print_server directory run the below command:
After running the command it will start the print server and show a message similar to below:
You may receive “Unrecognised command PHP”, in that case, add PHP command to your environment variable. (Google search result)
- Now we are ready to go. Try creating a test sell from the pos screen and it should print in your thermal printer. If you haven’t added a printer then follow the steps mentioned in “Step1: Adding a Printer” and it should work.
Great, now we’re ready to print on a thermal printer.
Give it a test drive.
Go to POS screen, add a test invoice and check if it prints. If not please check if the pos receipt server is running or not.
