A php class for printing out labels on Brother P-touch printers

Supported models include (PT-P700, PT-H500, PT-E500)

The code is being developed / tested using a PT-P700, but the protocol should be the same on all three models.

The php class is intended to be used as part of a web page allowing it to print labels on a printer connected to the web server.
However the code also includes some php scripts to allow printing from the command line.

This is NOT A CUPS DRIVER nor is cups or any other printer systems required to print.

Requirements

• PHP
• libusb module for PHP see: php-usb for details on installing it
• GD module

sudo apt-get install php5 php5-gd

Note:
The user running the command/script must have permission to use the USB device.
Please consider looking into using udev to grant you permission to use the printer.
Alternatively you can test the script using 'sudo'.
