There is only a single grayed out file in the screenshot and it has no extension listed, so it would appear it works fine with exception to an unsupported file type inside the folder.
I assume from the screenshot you linked that the EN-BP YOUR CHOICE.docx and the XeroxScan00X.pdf files are are working fine
For simplicity sake, here is your file embedded so we don't need to bounce between tabs/apps here
So what format is the file in question that appears to have no extension and therefore would not be expected to work?
As stated in the subject of this post, it is a Google Doc file. I guess they don't show up with file extensions.
I would have expected support for the native file formats from Google.
The native format is docx, but they support many, the issue you may have is that you are not actually saving the files (download) so it fails to have an extension as one was never chosen. I'm not sure if the printer can handle the .odf format, it would make sense (being an open format) that it may be what the unsaved state is even though it isn't at the top , nor is it the default when downloading the file (.docx). Maybe one of the App Gallery people here will speak up on that point.
You're in the "Download As" menu there. As a user, I'm not going to download the document to my PC and add it back to Google drive as a docx just so I can walk up to the machine and print it from the app. I'll just print it from my PC but it reduces the utility of the app if I can't just print Google Docs. I would have expected the app to be able to use that "download as" capability itself somehow to convert to whatever format it needs to be able to print.
Unfortunately, it turns out that Google Docs, Sheets, Slides, etc. have file extensions that we currently do not support. While we look into how to fix/support this, as a workaround you can download the files and then drag/drop or upload them back into your Google Drive account and then you should be able to print them (as your last post mentioned).
Sorry for the inconvenience! Look for a post on this thread for an update on when we should have a fix for this.
Thank you for the message.
