These increments reflect the history of twentieth century printing. Pitch,
referring to the number of characters printed ineach horizontal inch, derives
from how typewriters space their characters. Lines and
columns were first
used by earlier computer printers (on which they are called horizontal and
vertical motion indexes). You already know about the Star LaserPrinter 4111
beingabletoprint300dots tothe inch.And the unitby whichtypesettershave
measured text for centuries is the point,
about l/72nd of an inch.
One hint aboutmoving theprintposition:youcan confuse yourselfif you use
more than one or two different units during the same session. So decide
beforehand how accurately you need to move the print position (not forget-
ting any graphics you want to include).Then stick to the unit(s)you choose.
The commands that move the print position in all these ways are described
in chapter 4.
2.4 CONTROLLING THE PRINTING
The CHARACTER parameter defines font attributes and setup values (if
any) for the Star LaserPrinter 4111.
A font attributes or characteristics determine what that font will look like
when it is printed. The next chapter, “Fonts”, explores the details of all font
attributesinmore detail. But let’shave aquickoverviewnow, because you’ll
meet these terms on the control panel program menu.
Font attributes: a preview
Orientation (portrait or landscape as described earlier) is usually thought of
as one attribute of a font; it’s not really a page formatting issue. Besides
orientation, the fonts with which you print have these attributes:
Symbol ser is sometimes called “character set” — which can be confusing,
since some people say “character set” when they mean a font. Symbol sets
are subgroups of a font’s symbols that are most appropriate for particular
countries, such as the UK (f), France (a), Latin America (ii) or Japan (Y).
Spacing and pitch are linked. Characters can be spaced on the linepropor-
tionally, so a narrow letter such as i takes lessroom than a wide letter like W,
Or characters can be spaced all the same width:twelve characters to the inch
is the monospaced spacing called 12pitch.
