Regional & printer note

Will a printer recognize 6 × 8?

6 × 8 may appear as 6R in photo-print services and as na_index-4x6-ext_6x8in in PWG media naming. Home-printer support depends on the tray and custom-size limits.

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.
