These units are equal to 1016 units per inch. Scaling allows you, the user, define an easier value to use. You can define a coordinate system that uses 1 unit per inch, centimeter, millimeter or just a rounder number such as 100, 200, 500, or 1000 units per inch. Overall, scaling lets you define an easier to calculate coordinate system. LEGEND: Ec = [Ctrl] [P] [Esc] in DOS EDIT EcE Resets printer. Ec%0B Enters HP-GL/2 mode using the default picture frame size and anchor point. IN; Initializes HP-GL/2 mode. IP0,0,2000,2000; Sets P1 to (0,0) and P2 to (2000,2000). SC0,10,0,10; Sets up user-unit scaling to range from (0,0) to (10,10). SP1; Selects pen number 1. Even though there is no physical pen, the SP command must be used to enable printing. PA5,5; Begins absolute plotting from the center of the square (5,5). CI3; Prints a circle with a radius of 3 user-units. IP2500,500,3500,1500; Inputs a new P1 and P2 position for printing a smaller circle. PA5,5; Begins absolute plotting from the center of the new square (5,5). CI3; Prints the second circle with a radius of 3 user- units. Ec%0A Enters PCL Mode. EcE Resets the printer to complete the job and eject the page.
