Matlab not responding, warning 'printer startup is taking a long time'

Why my matlab R2018b on Win10 get stucked after running any code, then after about 10 minutes it shows the following:

Warning: Printer startup is taking a long time. Check
whether your default printer is online. Or set your default
printer to print to PDF.

I check my win10 is setting printer as 'Microsoft Print to PDF', and the function 'printopt' gives

'COPY /B %s PORTPROMPT:'

Is there any setting wrong causing this issue?

I did not find out how to solve this.

But after re-install my windows, the problem was fixed

I faced same strange problem, however, by setting a default printer from the control pannel has fixed the issue.

This does not fix the problem for me.

I often faced the same problem once changing Wifi environment. You can close Wifi to try again when open MATLAB, and it worked in my computer.
