Regional & printer note
Will a printer recognize Half Letter?
Half Letter is also called Statement, Mini, or Invoice in software and printer menus. PWG maps these aliases to na_invoice_5.5x8.5in; always verify the dimensions rather than relying on the label.
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.
