Editing Device Type Formats
To define a device format, do the following:
With formats for ABAP lists, you can edit the following attributes:
Attributes: If you are working with any type of PostScript printer, make sure that PostScript format type is selected for formats for ABAP lists. Do this for every PostScript device format by choosing
Attributes from this screen and selecting the appropriate field.

With PostScript formats that use the printer for list printing, do not select the field PostScript format type.
Editing actions: You can make changes to actions by double-clicking an action. When you do so, the system opens a programming editor in which you can make your changes. Your source for the device-specific commands that you need to enter should of course be the technical guide or programming manual supplied with your printer or fax machine.
Before you edit any actions, read important notes.
You can include actions from other device formats with the \I command. You can find more information in the special characters note.
Driver for List Formats
From Release 4.5A, special drivers in the R/3 kernel now control the format of lists (this is no longer handled by formatting actions). The drivers can now interpret page formats and paper tray information. You can also print icons, symbols, lines and colors in lists using these drivers. You can change the attributes of the formats that are passed onto the driver, such as margins and font sizes.
The new drivers can also interpret paper tray specifications in the printer definition and adapt the selected format to an existing paper format.
If you copy one of the device types HPLJ4000, KYOFS170 or POST2, you can specify in the device type definition that the list printing driver should use all the list formats.
However you can also choose to assign the suitable list printing driver only for specific device type formats (for device types HPLJ4000, KYOFS170 or POST2). To do this, proceed as follows:

If you specify the values yourself, each character is set individually during print formatting. This reduces printer performance considerably.
