The Merge Documents window has a timeout value of 10 minutes to allow the user to merge the document.
In the current PDF Printer Driver, one cannot adjust the timeout value in the Printing Preferences or the Printer Manager.
One can adjust the timeout value by editing the Printer Driver INI file.
The Printer Driver INI file is usually placed in the following location:
On both 32-bit and 64-bit Desktop operating systems
C:\Windows\System32\spool\drivers\w32x86\3\BuPiniNT.ini
C:\Windows\System32\spool\drivers\x64\3\BuPiniNT.ini
Open the INI file with any text editor as an Administrator (such as Notepad), and edit the “Merge Window Timeout” value.
The timeout value is specified in minutes, therefore for example if you would like to increase the timeout value to 30 minutes, it should be the following:
Merge Window Timeout=30
Save the INI file.
To apply the new Timeout value, you must restore the default settings from the INI file.
To restore the default settings from the INI file, please perform the following steps:
On Windows 10, please navigate to:
1. Follow the menu path Start > Settings > Devices.
2. Scroll to the bottom of the page and click Devices and Printers.
Result: The “Devices and Printers" window opens.
3. Right-click on the Black Ice Printer Driver
4. Click Printer Properties
5. On the top Advanced Tab
6. Click Printing Defaults
On Windows 11, please navigate to:
1. Follow the menu path Start > Settings.
2. Click Bluetooth & devices
3. Click Printers & scanners
4. Click Black Ice Printer Driver
5. Click Printer Properties
6. On the top Advanced Tab
7. Click Printing Defaults
The press “Restore default”. This will restore the INI file setting for the current user only.
NOTE: Since the default settings are now restored from the INI file, you may have to enable the Merge feature again in the Printing Preferences.
