7–27Digital Emulation
Set Page Orientation (DECSPO)
ASCII Code ESC [ Ps & z
Hex Code 1B 5B Ps 26 7A
Dec Code 27 91 Ps 38 122
Purpose Sets the intended reading orientation of the page with respect to the
paper feed direction.
Discussion DECSPO is similar to the page orientation defined by PFS, but has no
effect on the page size or number of lines and columns. All page related
functions are interpreted in relation to page orientation (margins, line and
character spacing). The default value is Ps = 0.
The selective parameters indicate the following:
Ps Function
0 Portrait: Page orientation is in
line with the paper feed
direction
1 Landscape: Page orientation is
perpendicular to the paper
feed direction.
