Blank check stock
Blank check stock is security paper with no bank numbers printed yet. You add payee, amount, date and (when your bank allows) the MICR line with check printing software, then print on a laser or compatible printer.
Why businesses use it
You avoid waiting for pre-printed orders, keep check numbers under your control, and can switch accounts without reordering a full box of bank-branded checks.
Bank acceptance
Self-printed checks must meet your bank's MICR and format rules. Ask before you replace ordered checks. Never put full account numbers into a free sample tool.

Practice payee, amount in words, and print — no bank numbers, marked not negotiable.
