Coax Interface Menu
•
Alternate Set 80 - 9F . This selection determines if ASCII codes 80 hex
through 9F hex will be used as control codes or printed as standard
printable characters.
•
Printable (the default) prints the alternate set as standard characters
•
Control Code selects the alternate set to be used as printer control
codes.
Mono/Dual Case
MONO/DUAL CASE specifies the font as MONO Case or DUAL Case (the
default). It is available only in non–SCS mode. The host will be notified of the
change when the printer is made READY. If the character set is one of the
following ‘right to left’ sets, MONO CASE prints the same as DUAL CASE:
Katakana, Hebrew, Hebrew Old, and Farsi.
SCS (System Network Architecture Character String) Mode is controlled by
the host computer. Refer to the
6400 Coax/Twinax Programmer’s Reference
Manual for more information about non–SCS mode.
Undefined Character Substitution
UNDEFINED CHARACTER SUBSTITUTION specifies the replacement
character to print in place of any unprintable character that is received from
the host.
The character code point can range from hex 40 to hex FE. The factory
default is set to hex 60.
Print Text Direction
PRINT TEXT DIRECTION specifies the direction in which characters are
printed on the page. This allows the printer to print languages which are
printed right to left instead of left to right.
•
CONTROL BY HOST (the default)
•
LEFT TO RIGHT
•
RIGHT TO LEFT
The “CONTROL BY HOST” option allows printers configured as a 4234 to use
the “SET TEXT ORIENTATION” command from the host.
When a RIGHT TO LEFT language is selected, the host will be notified of
print direction changes when the printer is made READY.
Image Buffer Size
IMAGE BUFFER SIZE (screen buffer size) allows you to select the following
image buffer sizes:
•
4K (the default)
•
2K
A POR status is sent to the host when the printer is made READY.
