PRIMA 2e Manual De Usuario

This prevents plugins from crashing the driver by attempting to use unsupported functions of a later 
driver release. 
 
Plugin version 
The plugin's version number is shown here. This is for support purposes to determine which 
version of the plugin is installed on the system. 
 
Unicode 
Some applications require to encode Unicode characters on the chips. This shows whether the 
plugin is capable of handling unicode data in the encoding string. If not, Unicode characters will be 
converted to Ansi by the driver. 
 
Description 
The plugin developer can display a short description of what the plugin does here. 
 

 
General information 
Each encoder hardware must be attached to a printer physically, either inside or outside. 
 
As each printer has its own ID, there is a fixed relation between one specific encoder and one 
specific printer. 
 
Since each encoder is also attached physically to the computer (USB, COM or any other possible 
port), a link of a "printer ID" and the "port" where the encoder hardware is attached on the PC must 
be created. This link is called "Port Assignment". 
 
In the Plugin Manager, the Port Assignment section shows two lists, one with all possible printer 
IDs and one with the available ports. Initially, both lists are empty. Depending on the encoder 
hardware and the ID of the printer to which the encoder is attached, the port names and IDs differ. 
 
Encoder ports 
The list is dynamically filled in real-time. That means as soon as a plugin is selected and an 
encoder, which is supported by the plugin, is attached, the port list shows the port name as a new 
entry immediately after Windows has recognized the device. For some encoders, it may be 
necessary to install the manufacturer's device drivers first. 
 

 

 
The same is true when a device is unplugged, i.e. the port disappears from the list.
