Transparency
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 the interface (e.g.
underlined text), or even down-loaded fonts.
There are two types of Transparency, Single-byte and Multi-byte. 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 AX-7 Cobra+ assumes
hexadecimal data until a terminating percent sign occurs.
Example (Multi-byte Transparency on IBM Proprinter):
You want the text to have an underlined part in the middle. Assuming
that you have an IBM Proprinter, ‘start underline’ and ‘stop
underline’ are defined by the ASCII codes $1B,$2D,$31 and
$1B,$2D,$30 respectively:
To access the Transparency function, Extended Emulation Mode
must be entered.
Printout:
Please refer to the manual for your PC type printer for information on
ASCII printer commands.
