on one line because of the semicolons.
CHANGING THE PRINT PITCH
In “printer talk,” character width is called pitch. Normally,
SG-lo/15 prints 10 characters per inch. This is called pica pitch
because it’s the same spacing as a standard pica typewriter.
SG- lo/ 15 can also print 12 characters per inch. This is called
elite pitch because it is the same spacing as an elite typewriter.
Condensed print is approximately 17 characters per inch.
Condensed pitch allows you to get 136 columns of printing on
an 8 ‘/z inch page.
Proportional spacing provides an alternative to the block-style
output of a defined pitch. It moves its print head only as far as
each character needs. Thus, the print head moves further for “M”s
and “W”s than for “1”s and “i”s.
The table below shows four options of this command.
