Abstract
Abstract A passbook printer uses a conveyor belt (16) to urge a passbook (86) towards a raised barrier (40) for the passbook (86) to strike the barrier (40) and then have one edge thereof aligned with the barrier (40) by sliding engagement with the conveyor belt (16). After alignment, the barrier (40) is lowered and the passbook (86) is advanced beneath a printhead and sensor assembly (38) which senses the orientation of the passbook (86) and prints thereon in a correct and upright manner regardless of the orientation of the passbook (86).
