Questions & Answers about O catálogo da galeria já está impresso.
Wait, isn't the past participle of imprimir supposed to be imprimido? Why does this use impresso?
When would I use the regular form imprimido instead?
Does impresso need to agree with the subject here?
Yes. Because it is used with estar, the past participle acts like an adjective describing the subject. Since o catálogo is masculine and singular, you use impresso. If the subject were feminine, like a fotografia, it would be já está impressa.
Could I use ser here and say O catálogo já é impresso?
Not for this meaning. Using estar describes the final state or result of the action (it is currently in a printed state). If you used ser, it would describe a routine passive action, meaning something like The catalogue is generally printed (as opposed to being digital).
