With the latest release of dslrBooth for Windows you can now easily and quickly pick printer, paper size, orientation instead of having to go to the control panel to do this.
Additionally dslrBooth no longer overwrites your chosen paper size. This is a good thing! This is import for those that are using commercial photo booth printers that would like to use the 2×6 cutting feature by changing the paper size. Printer settings are stored across restarts so set them up once and forget about them if you’re not changing your layout.
As the developer stated himself, "We’re all about streamlining things in case you haven’t noticed"
