HP 5961-0509 manual Adapting the HP-GL/2 Coordinate System to, Match the PCL System

	Adapting the HP-GL/2 Coordinate System to
	Match the PCL System
	The following example uses the IP and SC commands to change
	HP-GL/2 coordinate system to match the default PCL coordinate
	system. The IP command is used to invert the Y-axis so that the Y
	values increase as the pen moves down the page. The SC command
	equates user-units to dot positions (300 dots-per-inch). The example
	draws a few lines in both PCL and HP-GL/2 modes to demonstrate
	that the coordinate systems are lined up correctly (the end points of
	the lines intersect).
Notes	Sending an IN (Initialize) or DF (Default) command causes the
	coordinate system to revert to the HP-GL/2 default.
	Since this example is based on the default top margin and text length,
	changing the top margin or the text length moves the two coordinate
	systems out of alignment.

to Match the PCL System in Portrait Orientation
ECE	Reset the printer.
EC&l2A	Set the page size to letter.
EC&l0O	Specify portrait orientation.
EC&l0E	Set top margin to 0.
EC*p0x0Y	Move to position (0,0).
EC*c5760x7920Y	Set picture frame to 8’’ x 11’’ (size of
	logical page).
EC*c0T	Set picture frame anchor point to
	current PCL cursor position (0,0).
EC%1B	Enter HP-GL/2 mode with the HP-GL/2
	cursor or pen at the PCL cursor
	position.
