Black Ice Printer Drivers can merge/combine multiple print jobs in the background silently into a multipage file, as long as the selected file format supports multiple pages, such as TIFF, PDF, and so on.
In order to combine multiple print jobs in the background, please navigate to Control Panel > Devices and Printers > right-click on the Printer Driver and select the Printing Preferences option > Filename Generation tab.
Set the Black Ice Printer Driver Filename Generation Method to one of the Exact Filename methods, such as Exact Filename, and enter a fixed document name that the Printer Driver can use for the output file.
Check the Combine/Merge multiple documents into a single file option and select the Merge documents into an existing file silently in the background option from the drop-down menu.
Print multiple documents to the Printer Driver. If the filename specified in the driver already exists, subsequent print jobs are appended to that file. If the file does not exist, the first print job creates the file, and the following print jobs are appended to the file.
NOTE: If the PDF file is password-protected, appending fails.
