Sets the darkness of drawn images.
It does not change the resolution of the image (logical pixels),
only the darkness of the segments drawn.
NOTE:Psh and Psv do not affect the density of plotted text.
Text density comes from the current font.
DECSGD sets the density for graphics (sixels, logos, vectors,
block characters, and bar codes). The selective parameters,
Psh and Psv, designate the horizontal and vertical dot
densities used for plotting graphics.
•
Psh Parameter (Psh) selects the horizontal dot density.
•
Psv Parameter (Psv) selects the vertical dot density.
The actions of Psh and Psv are dependent on the print
orientation because x-direction print densities differ
significantly from y-direction print densities. (This is the only
printer instruction that is directly dependent on the current
orientation setting.) Table 6 defines how orientation is
designated by Psh and Psv.

Use Table 7 and Table 8 with Table 6 to establish the exact
orientations designated by Psh and Psv.
