Transparency
IBM PC Support Virtual Printer is one way of sending data
transparent to the printer. This method is always active and is not
described in this manual.
This section describes the AX-3 Cobra+ specific transparency
methods.
The Transparency function allows you to send data directly to your
printer without any conversion (pass-through). The data could be
ASCII printer commands unsupported by AX-3 Cobra+.
Be careful when using the Transparency function for generating
printable characters, selecting fonts or making text positioning. The
AX-3 Cobra+ supports these functions in normal emulation mode,
and your settings may be overridden by the system.
The transparency function is mainly intended for down-loaded fonts,
printing logos and forms and similar applications.
The function is accessed in Extended Emulation Mode.
The Single-byte Transparency function is called by a percent sign in
your document (‘%’) and it will pass through one subsequent ASCII
byte (hexadecimal).
The Multi-byte function is started by two successive percent signs.
When the start sequence (‘%%’) is found, the AXIS AX-3 Cobra+
Cobra assumes hexadecimal data until a terminating percent sign
occurs.
