Issue with printed PDF (bold text)

Give this a try: boot into Safe Mode according to How to use safe mode on your Mac and test to see if the problem persists. Reboot normally and test again.

NOTE 1: Safe Mode boot can take up to 3 - 5 minutes as it's doing the following; 

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts 

• Deletes font caches, kernel cache, and other system cache files

NOTE 2: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. This makes it act as a wired keyboard as will insure a successful boot into Safe Mode.

Perhaps updating to Jan 13, 2023 release of Ventura may or may not fix the Preview Issue

Links below pertains to updates

Keep your Mac up to date - Apple Support (CA)

About the security content of macOS Ventura 13.2 - Apple Support

Agree on the macOS side of the equation.

This is only IMHO and does not come with a Technical Knowledge of the Inner Works

macOS is still being offered on Intel Computer hough Apple is moving to Apple Silicon CPUs .

As long as Both Platforms are running side by side - the Apple Servers may need extra time to desert what update elements are needed for which Platform.

The work Pre-work ( Server Side ) required for the delivery to End User is also extended

IOS side - this would not apply

While it is supposed to be very accurate, PDFs aren't perfectly rendered.

I doubt it would help, but have you tried printing it to PDF, then printing that PDF. Compare the two visually and see if the extra boldness appears in the Print to PDF version onscreen.

Preview doesn't handle all PDFs and all PDF capabilities. Acrobat Reader should be the standard. If it is also do that, I don't know why. I suppose it could be something to do with the rendering for the printer.

Sadly, in my experience, since about macOS 11 Big Sur the Software Update Applet is sometimes not reliable.

Maybe it ( Software Update Applet ) is still Leaning lol

Sell correction, should read Jan 23, 2023
