Category: Virtual Printer Hardware

RedTitan provides the “glue” that transforms electronic documents and helps migrate legacy printer data to electronic medical record formats so it was no surprise to get a call from Zeiss with a interesting challenge. Some of the equipment made for the ophthalmology industry could not produce an electronic document, all it could do was print!

Surely a software upgrade and perhaps a TCP/IP hardware interface
would be good enough?
No – you don’t understand – If we change anything it has to go back
through the very expensive TYPE APPROVAL procedure.

It turns out that the world is full of “black box” devices in medical and industrial applications that can only print. Sometimes the law or security prohibits any attachment to a network. (nobody wants a “virus” on an ophthalmic lance) – The concept of Virtual Printer hardware was born.

The principle is easy enough. Build a small piece of hardware that just looks like the same old printer to the “black box”. A powerful microprocessor handles the printer interface – we used a MICROCHIP PIC 16 device. Data is collected on a USB connection to a PC controlled using an FTDI package. The device gets its power from the USB interface avoiding the need for a special power supply.

Of course data collection is only half the story. Processing the collected printer data is the work of RedTitan EscapeE. You can even recover data straight off the printed page for re-processing, filing or even patient identification.

Now, six years on, many thousand of these devices have been rolled out in data capture applications. The chances are that, the next time you take an eye test, you will find the RedTitan Printt2PC box doing its job in the back of a Zeiss Humphrey Field Analyser.

Today RedTitan offer various models of the Print2PC system – Parellel Port, USB Port, Serial Port and Network attached printers, taking care of everything from Pacemaker Programmers through to Blood Analysis controllers. There is even a bowling alley on an island in northern Germany that owes its scoring system to Print2PC.
