Would that be common in that area?
They're not common, but I've been in a couple of shops with multiple large-format printers. They are basically giant ink-jet printers.
Maybe Hezbollah bought several of them to make posters for demonstrations?
Also, it is a common practice to apply a laminate overcoat to the paper to make them more durable. It might be possible to interpose elements between the laminate and the paper.
