20 User Setup Utility
Emulation
❏
Select either standard emulation or IBM emulation.
Note that the emulation you choose determines the character set and printer
control commands that are applied for printing. See “Character Sets” on page 60
for the character sets used by each type of emulation. See “Printer Control
Codes” on page 66 for details on printer control commands.
Unless you specifically need the IBM character set, we recommend that you
normally use Standard emulation. If you select IBM emulation, you will also
need to select an IBM printer driver.
NLQ Direction
❏
Select either unidirectional ( Uni-direction ) or bidirectional ( Bi-direction )
printing for NLQ (Near Letter Quality).
Bidirectional printing is faster, while unidirectional printing generally provides
better print quality.
A.E.C.
❏
Switch A.E.C. on ( Enabled ) or off ( Disabled ).
The letters A.E.C. stand for Automatic Emulation Change. As its name
suggests, enabling this feature tells the printer to automatically select the proper
emulation mode (standard or IBM) to match the printer driver selected in the
application you are using.
