PHP is an open-source programming language that makes it easy for you to install and use a thermal printer. Because of its open-source applications, it also supports other types of printers, such as ink jet, multifunction and label printers. You can easily install a thermal printer in your network, even if you are not fully knowledgeable in PHP programming.

Step 1

Connect your thermal printer to your computer. Make sure all cables are tightly connected to your computer ports before setting up your printer in PHP.

Step 2

Install all of the necessary drivers for your printer if it is not plug-and-play. Some newer operating systems, such as Windows Vista and Windows 7, should automatically install it for you, but always be ready to do it manually if that doesn't happen. Consult your printer's manual for instructions on how to install drivers.

Step 3

Use the following code to install and use your thermal printer in PHP:

$handle = fopen("PRN", "w");

fwrite($handle, 'text to printer');

fclose($handle);

This code establishes the connection with the receipt printer through PRN, writes to the receipt printer through the file handle, and then disconnects the printer after printing your document.
