Well this problem with garbled Helvetica in printed output (see images in prior post) is fixed if we DISABLE font embedding ... with this:

void QPrinter::setFontEmbeddingEnabled(bool enable)

Two questions:

(1) Does that given any insight into the problem we are having? (This is with Qt 5.5.1).
(2) How reasonable is it to DISABLE font embedding? Will that cause any problems for our users?

Thanks in advance.
