With the 3.27 release, additional paper sizes have been added to the advanced
print options. The expanded paper size availability is accessible regardless of printer brand.
We've added an additional print paper size under your advanced print options. Along with the existing sizes (A2, A4, A6, PRC/Kaku/Chou/You envelop sizes, B6, 12x11, and 180x210mm), anyone with the 3.27 update now has access to the 170x210mm size.
