To better understand the way the print modes work, consider
that each mode except pica (pica is the default) has a separate
switch that can be turned on and off via software. Once the
switch is on, it stays on until turned off. However when two
modes that conflict are turned on at the same time, the printer
must choose which one to use.
For example, suppose you turn on both Condensed and
Emphasized modes. These cannot combine, so the printer
must make a choice; in this case, the printer chooses Empha-
sized.
Summary notes
1) Pica is the default pitch and is active when Elite is turned
off.
2) When two modes conflict, the one of lesser priority
bit-wise is cancelled. For example, Condensed and
Emphasized cannot be printed at the same time,
printing is Emphasized.
3) Elite cancels Emphasized.
4) Underline, Italics, and Expanded modes combine with
any print modes.
