PAGE COORDINATE SYSTEM

Before PPL III commands that involve print positioning can be understood, the PPL III page coordinate system must be understood.

This section of the PPL III chapter covers the following subjects:

▪ Coordinate system model

▪ Active position, positioning controls, and advance increments

▪ Coordinate system bounds

▪ Limits of the printable area

▪ Logical page to physical sheet mapping

▪ Variable paper size mapping

▪ Minimum print area size

▪ Character adjustment using the First Character flag

▪ Partial line motion

▪ Side effects of positioning controls

▪ Conditional Form Feed

▪ Conditional Sheet Feed

▪ Page break

The page coordinate system defines a logical page. The relationship between a logical page and physical printed pages is determined by the paper size.

Coordinate System Models

There are two coordinate system models – the character cell model and the point model.

▪ Character Cell Model: A position comprises an entire character extent. The addressable increment is the entire character.

▪ Point Model: A position is a dimensionless location and the addressable increment is not directly related to characters.
