Could you please provide more information about the another PDF printers?
Is it a three-party virtual printer?
Does this issue occur with other Office files? Such as Word documents, Excel workbooks.
It's recommended to open Paint > Simplly doodle on drawing > File > Print > Select "Microsoft Print to PDF" to print for a test.
If this issue just occur with Office files, I suggest you go to Control Panel to perform an Online Repair for Microsoft 365 apps first.
Please also go to Start menu > Settings > Devices > Printers & Scanners > Click the "Microsoft Print to PDF", Manage > Set as default.
Beisdes, please remember to turned "Let Windows to manage my default printer" off.
Any updates you may post back.
