Hi,
[quote user="quasi_modo"]Is it possible to open some .dgn-files using the command "OpenDesignFileForProgram" and print them?[/quote]
I agree with Jon it's not good idea and I am sure it brings more problems than benefits. OpenDesignFileForProgram is not equal to opening of active design file and some functionality is not available. To ensure the model will be printed correctly, I assume you have to open it normally.
[quote user="quasi_modo"]What advantage could Print organizer give us?[/quote]
It's really powerfull tool with plenty of options and functions. If used with sheets, the printing process can be fully automated including pen tables, using Named Expressions e.g. to define output names etc.

It's not clear what your situation is (what steps you have to do and how print parameters are defined). But if you need to implement some pre-processing, I guess it can block PrintOrganizer usage. But I have not researched VBA cooperation with PrintOrganizer yet. For sure you should exactly define what MicroStation version will be used, because both print options and VBA API has changed in versions.
With regards,
Jan
