Star Micronics SK1-321
Compact 3-inch receipt, ticket, and label printing for space-constrained kiosks

Compact Paper-Basket Design
Drop-in loading for tight enclosures
The integrated paper basket keeps servicing straightforward where roll-arm clearance is limited.
Two Output Configurations
Standard-left or right-hinge layout
Both configurations use the same print engine, interface set, and electrical integration so the enclosure layout can drive the selection.
