Is there a way to use my android phone as a parallel printer?

[Android Central Question]

I have a Digital Alarm Communications Receiver with a parallel printer output. I would like to use my android phone or tablet as a printer to dump the DACR information to.

I have an S10 phone and a Galaxy Tab Active2. The DACR is Sur-Gard MLR2-DG

After reading up on what that device is, that's way beyond my scope of knowledge. You might want to contact the company and see if they know of a solution for you: https://www.dsc.com/index.php?o=contact

I guess one of the questions needing to be answered - what is the output currently connected to? What is the format of the data.

Connecting the hardware is only a portion of the process. Getting the phone to recognize the data and log it to a file that can be read is an entirely different beast and likely requires a new app to be developed.
