Unless you get a dispenser module add-on, you'll need to silkscreen / screenprint solder paste onto the PCBs. Most PCB stencils are made of stainless steel and last years. Right now we make our stencils out of kapton (polyamide) with a laser cutter
You can also get this done for you as a service from Pololu, or Ohararp It should be $20 or so for a small sheet.
