Star Micronics 4111 Applications Manual page 72

The laser printer just zips down this chain of attributes one by one,
eliminating fonts that don't match what you want, until it gets down to one
unique font that matches your request. If the printer matches down to, say,
style or weight but can go no further, it will give you its closest font to your
request.
And if you don't specify a particular value for some attribute, the printer
assume'syou want the value that attribute had in the last font you specified
(or the default value if you'vejust turned on the printer). This can save you
some effort: if the font you want has an attribute the same as the current font,
you don't have to specify that attribute again.
Orientation
Portrait orientation prints text across the width of a page. Landscape
orientation prints text sideways up the length of a page.
The Star LaserPrinter 4111 is more flexible about orientation than most other
laser printers; it lets you simply rotate any portrait font to the landscape
orientation or vice versa. To start you off when you change orientation, the
printer resets all its margins and its column and line definitions to their
default settings.
When you want to select the opposite orientation, send this command:
<ESC>&t'n O
in which'for n you put Oto get portrait orientation,
1 to get landscape orientation,
2 to get upside-down portrait orientation,
or 3 to get upside-down landscape orientation.
(Notice: the t'character after the& is a lowercase L.)
