In GL/2, the coordinate system can be set by the user. The default coordinate system has its origin at the lower left of the picture frame (P 1), with its x-axis horizontally to the right, and the y-axis vertically upwards.

Two types of units are available, plotter units (default) and user units. A plotter unit is 0.025 mm (0.00098 inch, 0.294 pixels at 300 dpi). User units can be set as required, different for the x and y axes, using the SC command.

When importing an existing GL/2 file or creating an GL/2 image within an application, you use several Escape sequences to set up the picture frame size, choose the picture frame location, and enter and exit GL/2 mode.

5 EG m

The following escape sequence is used to enter the GL/2 mode:

<ESC> % n B

If n is Oor an even number, the cursor is set to its previous position when using GL/2. If n is 1or an odd number, the cursor stays in its current position. When n is Oand the printer is entering GL/2 for the first time, the default cursor position is P 1, the lower left corner.

This command sets the cursor and causes subsequent GL/2 commands to be interpreted as commands, not text to the printed. The printer remains in the GL/2 mode until an exit or reset command (see below) is received, or until the printer is switched off.

To exit the GL/2 mode, use the following escape sequence.

<ESC> 7Cn A

If n is O(or an even number), the cursor is reset to its position before entering GL/2; if n is 1 (or odd), the cursor remains at its current position. After this command, subsequent GL/2 commands are treated as text and will be printed.
