Print Controls 
Print controls are generic formatting indicators for print operations such as activating bold, changing the font size, and so on. During formatting, the generic indicators are replaced by the printer commands required by the specific device type. Essentially, print controls, together with device type formats, make up the language for the SAP formatting of an available printer or other output device.
To have a new print control used in a document, you must either program its use into an ABAP report or program or have the print control inserted in SAPscript documents. In SAPscript, users can explicitly insert a print control or it can be inserted in the definition of a SAPscript form (form).
Creating a New Print Control
If you are defining a completely new print control, you need to do the following:
...
1. Add it to the Standard print controls.
Procedure: Entering a Print Control in Standard Print Controls
2. Implement it in the device types in which it is needed. Implementing a print control requires simply that you specify the print command(s) that are to be triggered by the print control.
Procedure: Adding Print Controls to a Device Type Definition
3. To activate the new print control in the SAP system, add it to the ABAP reports (with the PRINT-CONTROL statement) and SAPscript forms (in window texts with /: PRINT CONTROL <Name>), or the standard texts in which it is to be used.
Changing Print Controls
Changing the definitions of existing print controls (for a new device type, for example) is simpler than adding a new print control. You need only edit the print controls in the device type in which they are required.
Do not change print controls in a standard SAP device type. Do this only in a new device type or a copy of an SAP standard device type.
Procedure: Specifying Escape Sequences for Print Controls
