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).
