Can you post a screen shot? Also, be aware that the internal PDF generator substitutes the Google Noto font, in order to accommodate all 70 languages. When you view or Print, you are using system fonts. Depending on when your last update was before this one, you might not have seen that.
What version are you using? (Manager sometimes updates several times in a day.)
If you’re on a Mac, use the built-in screen grabber: Command + Shift + 4 keys simultaneously, then drag over the image to copy it. Then use Preview’s markup toolbar to obscure proprietary information. If there is a problem, no one can help unless we can see it.
No, I’m not using a custom theme. I know how to take a screenshot on a Mac, but unfortunately the proprietary information (customer name, address, and order details) is the very data that is not displaying correctly, and therefore I can’t really upload it here. Ironically, when I create a fake customer and create a fake invoice with fake details it does display correctly. There must be some bug with displaying existing customers and existing inventory, but I cannot screenshot that here. Catch 22.
I’ve noticed this issue as well, with the built-in PDF generator. It started a while back when fonts were changed to support additional languages, I think. Earlier this year / a few months ago.
Had been working around it with the Print button, assuming it was an issue only for me.
Will reproduce it with dummy data and then post screenshots here.
Notably, the ‘Preview’ app in macOS makes the problem most obvious (the default viewer for opening PDFs, images, etc). Dedicated PDF reading apps sometimes displayed the broken files properly, but any customers using macOS will likely be using ‘Preview’.
Notice that boldface type is not displayed. The Noto font is not substituted, nor is the screen display font used. Some other font is substituted. Characters are cut off. And spacing is irregular. But, if a second PDF is generated, everything functions normally:
There is a known bug: 1st PDF in session renders incorrectly - #12 by lubos. Read the thread about this bug and see if your appearance of Comic Sans font is similar. In other words, does the problem appear on the first PDF of a session and then disappear? If so, it is almost certainly the same problem, but the appearance of that specific font (which others have not seen) may shed additional light on what the problem is.
The latest version (18.8.69) is fixing the issue where the first PDF document didn’t have correct font.
I’m also removing Google Noto fonts. The original reason to add them was to avoid crashing bug on Mac OS X due to 3rd-party library. Now that bug is resolved, the fonts no longer needs to be part of Manager installation package.
I suspect there could still be an issue where some scripts on Mac OS X might not show correctly in generated PDF but that’s something I will address separately case-by-case.
