Page setup button in Acrobat alt-tabs me to my desktop instead of staying in Acrobat

I have been noticing this issue over the past few days and I’m not sure what is causing it.

We have a networked Canon ImageRunner printer that I print PDFs to. Lately, when I click the page setup button to select the correct paper size and orientation, Acrobat has been “hiding” -- basically it moves to the background and forces the desktop as my active app. I have to alt-tab back to Acrobat, where the page setup dialog box is open and waiting for me.

I would expect it to just open the page setup box and NOT move to the background.

I did just realize today that, if I do anything else first, such as click the Properties button next to the printer name drop-down, then cancel out of that and then click the page setup button, it behaves normally. But, if I click the page setup button first, before anything else, this odd behavior happens.

Just started noticing it this week. Nothing has changed with our printers or network setups or anything.

Anyone else having this issue?

    Hi there 


    Hope you are doing well, and thanks for reaching out and sharing the detailed report. That clue about the Properties button workaround is really helpful and tells us a lot about what's happening here.

    What you're experiencing is a focus-stealing issue that can occur when Acrobat first initializes communication with a networked printer driver during a session. The Page Setup dialog technically belongs to the printer driver, so if the driver hasn't been "activated" yet in that session, Windows can hand focus over to the wrong window when the dialog opens. The Properties button workaround works precisely because it forces that handshake first.

    Here are a few things to try and see if that works:

    1. Update or reinstall the Canon printer driver
    Since this started recently and there were no other changes, a driver update may have introduced a focus-handling regression. Head to Canon's support site, check for the latest version of the printer driver for your ImageRunner model, and do a clean reinstall (remove the existing printer first).

    2. Set the Canon printer as your default printer
    Go to Settings > Bluetooth & devices > Printers & scanners, select your Canon printer, and click Set as default. When Acrobat opens the print dialog, it may be initializing focus differently for non-default printers.

    3. Repair your Acrobat installation (Win Only)
    Open Acrobat, go to Help > Repair Installation, let it complete, then restart. This rules out any corrupted preference or component file that might have changed around the same time you noticed the issue.

    4. Reset Acrobat's preferences
    Close Acrobat, then navigate to %AppData%\Adobe\Acrobat\<version>\Preferences and rename (don't delete) the Preferences folder to something like Preferences_old. Relaunch Acrobat, and it'll rebuild fresh preferences. 

    5. Check for a recent Windows update
    Since it "just started this week," it's worth checking Settings > Windows Update > Update history to see if an update was applied around that time. Occasionally, Windows updates affect how dialog ownership is handled between apps and drivers.

    Additionally, let us know which version of Acrobat you're on (Help > About Adobe Acrobat) and your Windows version, that'll help narrow things down if the above steps don't fully resolve it.

    Thank you. I will try this out. One thing I noticed is that I couldn’t find an option in Settings to make that printer my default. However, I noticed that “Let Windows manage my default printer” was turned on via toggle. I turned that Off and noticed that “Default” then suddenly showed up under my Canon printer’s name, so it’s already the default.

    However, maybe turning off that toggle will help, too. I noticed that, after turning that to “Off,” “Make default” showed up next to my printer when I selected it. Before that, it only showed “Remove.”

    I’ll test this out before moving onto the other steps.

    Thank you!
