See if manually setting a default printer in Devices & Scanners makes a difference. Clear the option "Let Windows manage my default printer" (which simply means that Windows changes the default printer each time you select a new printer).

I have the exact same problem.
The problem first occurred some months ago and we tried all the suggestions on this and other threads but nothing solved the issue.
We have a work network with several printers installed and my own printer set to default, the option to manage is unchecked....my computer is running the latest updated version of Windows 10
Printing to my default printer works just fine with pdf's, from emails and also test pages print with no problem
Eventually we found a thread on a forum that suggested installing a 32 bit version of Office, we did this and the problem disappeared, I have had no problems for months.
Last week I performed an update on my Sage Accounts software and I was no longer able to export reports to Excel, - Sage customer service advised that my version of word was incompatible @ 32 bit so we have had to update now to the latest Office 365.
Now this no printer installed error has returned and I can no longer print from Word or excel to my printer...it simply says "we couldn't print because there does not seem to be a printer installed"
I have found a work around...I select the print to pdf (but not Microsoft Print to PDF as that does not work either, I have something called Nitro PDF installed), but even printing to this only actually works if I close Word down, re-open the document and
then attempt to print it again.
My job as Company Administrator means that I constantly work with Word, Excel & Sage and this is making my job very difficult to do, it is not a new problem and I am not the only one having this issue, please advise when this bug will be fixed as it is unacceptable.
