My issue would be, how to print it, in batch.
That has been a curiosity of mine too. You can embed images in HTML or PDF stream files, for example. But how do you send an HTML file, or a PDF file, to a printer, without first opening it in a browser, or PDF reader?
Batch is the question. What if the user doesn't want the manual step of opening the stream file, and printing it? Just sending the stream file to the printer automatically. And keeping the processing on IBM i, rather than using a PC to print the file.
