Device Management in BAAN ERP

Introduction
Generating output is one of the most important tasks of an information system.  Raw data is fed into the system and processed.  The processed data must then be sent to a suitable output device such as a printer, a terminal screen, or a file to be of further use.

Device Types:

Within BAAN Software the following Device Types can be defined:

• Printer (Physical Printer)
• Direct (also a physical printer but not handled by the print deamon)
• Logical Printer (set of physical printers)
• Append to File
• Rewrite File
• Screen
• Aux. Port

1) Screen Device

2) File Devices

There are two different File Devices:

• Append
• Rewrite

If required, you can make use of a converting program to convert the output into other formats, for example, ASCII format. 
The user may assign a name and directory path to the output file.

3) Printer Devices
There are three kinds of Printer Devices:

• Printer
• Logical Printer
• Direct

4) The Printer Device Types

A Printer Device is handled by the BAAN shell script lp6.1. This shell script contains the UNIX commands for different kinds of hardware platforms. To define a Printer Device, you have to specify the UNIX Spooler name of that printer, for example pr1001. 

The Logical Printer is group of physical Printers.

The Direct Printer is handled directly by UNIX. You have to specify the whole UNIX command like: /bin/lp -c -dpr1005 -n%d -s %s. See the paragraph on Maintaining Device Data for an explanation of this command. 

5) Device Queue and Printer Daemon

The Device Queue is the Tools Table ttaad320, which contains all the Print Requests. This table is used by the Printer Daemon to register the Requests and to handle them. 

• Device Queue
• Print Daemon
