Can’t print Word or Excel files from Dropbox.com

I respectfully disagree as I have found this issue to be isolated only to dropbox I have given the dropbox site full allow permissions in chrome and allowed all pop-ups for the dropbox site nothing I have found resolve this issue yes the user can open the excel document using the open document as PDF but print preview and regular printing using excel for web from dropbox should work it should not be blocked the user should not have to resort to workarounds the user I am working with would like to only use dropbox for certain shard documents if they open the files locally or using office online printing and print preview works every time but that is a workaround the problem I assure you is isolated to dropbox and drop boxes version of excel / word I can not seem to find mention of the issue other than this thread and no one seems to offer a follow up other then to pass the blame its same issue on both edge and chrome and firefox doesn't offer a print preview at all so that also wouldn't be a good work around for a user that just wants to use the features that should work via drop box and not switch to an other solution maybe instead of passing blame someone can give a real solution as the problem is not anything the do with locally installed office 365 or office 365 online they both work flawlessly with the same documents so tell me another one please didn't work with any of my real world test devices and yes same as other poster brand new install of windows 10 with no plugins nothing messed will default settings and also tried to give drop-box site full access by allowing acess to everything incuding pop-ups in chrome no dice. any help would be greatly appreciated very frustrated trying to make stuff work that just should do begin with without having to jump though hoops have tried disabling the firewall and have no AV on the test system also disabled windows defender still get blocked by chrome / blocked by edge no print preview for excel for web via dropbox any suggestions of anything else I would try with a windows based system???
