PTX Transparent Control
You can enable additional printer features that are not accessible through
standard Coax emulations. To access these features, send text commands in the
data stream. The commands must have a start and end code. Three sets (each
containing a start and end code) are available:
Set 1: start code =<%
end code = >
Set 2: start code =
end code = $
Set 3: start code = _%
end code = _
Change Case
CHANGE CASE specifies the font as MONO or DUAL case. 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: Katak., Hebrew, Old Hebrew, and Farsi.
SCS (System Network Architecture Character String) Mode is controlled by the
host computer.
Set Text Orientn
SET TEXT ORIENTATION 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
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.
