The Models class is basically an enumeration class that provides information about all the devices (only a few plotters for now) that are supported by the library.

Note: the only plotter that was tested so far is the HP 7475A. We are assuming the others are going to work based on the documentation we found for them.

If you have a plotter that is not listed here, contact the author to see if we can add support for your device. Adding support for a new model simply involves retrieving the information such as the one found in this class for other devices.

Characteristics for the HP 7440A plotter. This model is also known as the Color Pro Graphics Plotter. It is an ANSI A and ISO A4 plotter with an 8-pen carousel. Note that the paper size cannot be changed programmatically. It has to be changed by flipping a hardware switch on the back of the device.

Important: this model can be fitted with an optional Graphics Enhancement Cartridge which bumps its buffer memory to 1024 (instead of 60) bytes. The cartridge also adds support for various plotting instructions which are not supported by default. For example, without the cartridge, this model cannot draw rectangles, circles or arcs, it cannot set the pen thickness, etc.
