HP 5961-0509 manual SC, Scale

zXMIN,XFACTOR,YMIN,YFACTOR — Establish the user-unit coordi- nates of P1 and the ratio of plotter to user-units. XMIN and YMIN are the user-unit coordinates of P1. XFACTOR sets the number of plotter units per user-unit on the X-axis; YFACTOR sets the number of plotter units per user-unit on the Y-axis.

zType — Must be 2 for this type of scaling.

An SC command remains in effect until another SC command is executed, or the printer is initialized or set to default conditions.

Examples: The following examples explain the effect of several parameter selections.

(SC0,40,0,40,2) allows scaling in millimeters since 1 millimeter = 40 plotter units. Each user-unit is 1 millimeter.

(SC0,1.016,0,1.016,2) allows scaling in thousandths of an inch since 1 inch = 1016 plotter units.

While scaling is on (after any form of the SC command has been executed), only those HP-GL/2 commands that can be issued in ‘current units’ are interpreted as user-units; the commands that can be issued only in plotter units are still interpreted as plotter units. (The command syntax discussion pertaining to each command tells you which kind of units each parameter requires.)

The SC parameters are mapped onto the current locations of P1 and P2. P1 and P2 do not represent a graphic limit; therefore, the new user-unit coordinate system extends across the entire range of the plotter-unit coordinate system. Thus, you can print to a point beyond P1 or P2, as long as you are within the effective window. For example, you can print from the point (-1,3.5) to the point (5.5,1.5) as shown in the following illustration.
