Thank you for your post.
A file hosted on a server keeps all setting within that server. If you access the file as a guest, you are unable to change the default settings. Instead, you should consider creating a script that prints current record, and a script that prints records being browsed.
For changing settings such as printer settings or so the contents of global fields are set to a desired "start value", I create a script that makes all these settings. Then I use Filemaker Servers Schduler to run this script each time I upload back to the server after taking it down to make changes. (You can run a scheduled script immediately instead of at a set time.) Since this is run from a "host" session, these changes stick and this script gives me a "Restore to Factory Defaults" type of capability without having to take the database down off the server and open it directly with filemaker.
