How to change printer settings so they stay. My paper size changes do not stay after printing even after clicking Apply ?

The printer settings on your Adobe Reader app might have a different set up from your QBO Desktop app, bacmac15.

QBO uses the Adobe's settings when printing a document, especially if you're getting a PDF copy of your transaction right before printing it. This article from Adobe's support site will walk you through the steps: https://helpx.adobe.com/acrobat/using/using-pdf-printer.html.

You can also reset the QBO app data in case it keeps reverting back to the default paper size . Here's how:

1. Click File and select Refresh.
2. Once done, go to Help and choose Reset App Data.

Then, log back in and print a transaction to check if everything is already working fine. Please keep me posted if you have other questions.

Our point of difference is that we use the Standalone App on Win 10..    So browser settings do not apply.   It was all fine until latest 'update' from microsoft.

You can check if this is a browser-related issue, lukewelles.

There are instances that the error you've encountered is caused by the unusual browser behavior.

Here's how:

First, you might want to use a private or incognito window. This will help your program to run lighter since it will not record any data history.

Second, if the error still persists, you'll want to clear your browser's cache. This will help your program to start. Though, you'll have the option on what data you're going to delete.

Lastly, if the error still occurs, you might want to use a different browser. There are instances that the browser you're currently using is not working.

Let me know how these steps that I provided works on your end.
