AX-7 Cobra+
Theory of Operation
Print data from an IBM host is in a format that cannot be recognized
by PC type printers.
The AX-7 Cobra+ converts IBM control and character codes to ASCII
control commands and characters, which are recognizable by the PC
type printer.
Together, the AX-7 Cobra+ and the attached printer will appear to the
IBM host as an original IBM coax printer.
In addition, the AX-7 Cobra+ allows any parallel and/or serial device
to share the printer with the IBM Host. The printer sharing function
works automatically, using an optional cable.
The picture below shows a typical use of the AX-7 Cobra+ including
the printer sharing function.
