2 Character Printing

Control Panel Option

A new option has been added to the control panel under the Graphics category. The new option, Vscale, determines whether or not vertical block characters will be scaled to match the difference between the horizontal and vertical print densities. The option is necessary to be fully compatible with old QMS Code V version 1 boards that are still in the field.

Block characters are build to be printed horizontally at 60 x 72. When the characters are rotated and printed vertically, it is necessary to scale the characters to maintain the cell size of the character. Some QMS Code V version 1 boards do not handle this scaling, so that when a 5 x 7 block character is rotated and printed vertically, it will actually be 4 x 8. when the Vscale option is turned off, we will now emulate this.

Block Character

Block characters are printed by putting the characters to be printed into the <data> portion of a Graphics Pass. Thus, the Block Character Command is the same as the Graphics Pass Command.

Each block character is printed within a window which includes an appropriate amount of space for character separation. The block character window size ranges from 0.1 inches (0.25 cm) to 9.9 inches (25.15cm) in increments of 0.1 inch (0.25 cm). the character window includes 1 dot row or column of intercharacter space for every 0.1 inches in window size. That is, if the Graphics Pass command is ^M0505000, then the character window size will be 0.5 x 0.5 inches, including a 5 dot-column space to the right of the character (see Figure 1 on page 27).
