I usually only print A Size so my Default Printer is a HP Officejet 8610
If I send a Print to my HP Deskjet 9800 that can do B Size prints, then switch back to my HP Officejet 8610 for printing on A size drawings: I can no longer print out drawings to the HP 8610 (For A Size)
The printer starts and makes some noise, but does not print anything
If I close Inventor 2019 and open it I can print to the HP 8610
The same thing happened to me with 2018
It's driving me nuts (Short drive but still!)
Edit: Windows 10 Pro
Inventor uses Windows print drivers. You should have you IT support group make sure you have the latest print drivers for that printer and for Windows 10.

Update: Also the 9800 printer is not supported under Windows 10 and that may be causing the some of your issues. Meaning you may need to use a different print driver.

I did check - Windows 10 Device Manager says it has the current Driver
I see the HP 9800 listed on that HP page of Windows 10 supported drivers
I can print fine to it, I just cannot switch back to my HP Office Jet 8610 and print to it (the 8610)
(Without restarting Inventor)
One other point: It does not always work like this - sometimes I can print to the 9800 (for B Size) and switch back and it works.
It did this back in Windows 7 also for what that is worth.
And Both Printers are connected via USB Cable
