Scaling
Purpose Selects a new line spacing and different horizontal by vertical (H
x V) dot density from the standard 120 x 72 base density. (See
Comments below.)
Mode Graphics with a Standard Graphics Command selected
Format (cc) @ M
scale 00 (cc)-
(cc) Represents the Special Function Control Code
(SFCC). Enter the SFCC for your IGP
configuration.
@ Specifies one of the @ commands. Enter @ to
begin an @ command function.
M Specifies the Scaling command. Enter M to change
the horizontal and vertical scaling.
scale Represents the scaling parameter. Enter one of the
two-digit codes shown in Table 15 to select a new
scaling. For example, with an MVP printer, enter 02
to select mode 2, 120 x 72 (H x V) dpi scale.
Once the new scaling is selected, all printing
reflects the new scale in horizontal by vertical dots
per inch (dpi) until scaling is disabled or the IGP
returns to the Normal Mode.
00 Toggles scaling on and off. When 00 is first
entered, the scaling value as selected in the
scale
parameter is enabled if a printer is selected through
the “Prt to Emulate” option. When 00 is entered
again, scaling is disabled and the IGP returns to the
default scaling configuration.
(cc)- Graphics Mode CR. Enter the SFCC for your IGP
configuration followed by - to end the command
sequence.
NOTE: If the Code V Options “Prt to Emulate” is selected, scaling is enabled.
Comments Dot density varies by printer mode; selecting a different printer
mode selects a different horizontal and vertical dot density. This
varying density can affect graphic elements created in one
particular mode but printed in a different mode. Scaling permits
graphic elements, such as corners or boxes, to retain their
physical shapes and sizes when printed in a horizontal and
vertical density other than the base density of 120 x 72 dpi.
