Regional & printer note
Will a printer recognize A6?
Familiar in ISO-size markets. Postal eligibility depends on the destination and mailing service, not on the paper name alone.
Always match the document size, print-driver size, paper tray, and physical sheet. A driver can silently scale a page even when the preview looks correct.
