QUESTION: Dear Prof Cleggsan

http://en.wikipedia.org/wiki/Oscilloscope

1. Is it possible to interface Cathode Ray Oscilloscope (CRO) with a printer via USB, Serial port ?.

Interface cable between the USB/Serial port on the CRO Device with the Printer output device.

2. Could this be a useful function as certain waveform for electrical circuits can be Visualized, inspected as well as printed similar to a electrocardiogram ?.

Awaiting your reply,

Thanks & Regards,

ANSWER: I saw ZZ answer to you on this (from the allexperts browser listings) and I like his reply to you.

It is a good idea but fully implemented already in lots of medical instruments and some special design oscilloscopes.  

But as ZZ indicated, some software and/or hardware modifications must be included to get the screen image transformed into a data format the printer can accommodate.

QUESTION: Dear Prof Cleggsan

Thank you.

http://www.nhlbi.nih.gov/health/health-topics/topics/ekg/printall-index.html

Is it possible in real time to take print out of a Waveform (Sine, Square, Triangular) seen in the Scope display for some electrical circuits directed to a printer output device interfaced to the Digital Cathode Ray Oscilloscope Device ?.

Is it possible to interface a printer with a CRO Device directly and take printouts of signal waveform in real time without using a computer viz desktop, server, laptop, smartphone ?.

In ECG Medical Device, the Heart beats/pulses recordings are directly printed on the Graph Paper. Is this possible in a Digital or a Analog CRO Device without interface of a Computer and which is similar to a ECG Device i.e. Printing facility is inbuilt within the Electrocardiograph
device/machine.

Between the two oscilloscope modifications which system is more feasible to manufacture ?.

1. Inbuilt Printing Mechanism / Facility similar to a ECG/EKG device i.e. Graph Paper/s are inserted in the Oscilloscope device, A print soft button on the Oscilloscope will produce output on the Graph Paper/s from the Oscilloscope Device similar to a polaroid camera.

2. The Oscilloscope is externally interfaced with a Printer Device via USB, Serial Ports. A print soft button on the Oscilloscope will produce output from the printer interfaced with the Oscilloscope.

Awaiting your reply,

Answer
This is more of a marketing or application question than an electrical engineering question.

As you surely know by now with all of our Q and A that just about anything dealing with imaging and data collection and conversion of information to other formats that it is possible, technically, to do any and all that you have suggested.  The issue remains as to its feasibility, cost, development time, application and marketing channel.

Many institutions looking at the need for gathering printed or electronic results are planning around their internal requirements and reporting obligations to governments, insurance companies, customers, patients, donors and recipients.

Therefore, I think the question of integrated product vs external implementation is application and market need, both of which are beyond the scope of this electrical engineering allexperts column.

Good question; hope you find the answers you are looking for.
