Go to **Store Management > Store Settings > Store register**. 2. Under **Retrieve Current Printer Topology For Merchant**, select "1:1". ![Select 1:1 for Printer Topology on the Store Register screen](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-commerce-retail-264-0-0-production-enus/17d647fb-8988-49fb-9add-c4f4cc79c9e4/retail/images/rt_cms_printer_topology_1_1_merchant.png) ### Register Level 1.

If you don't have a printer initially, you'll still be prompted to select a printer at the beginning of the session. If printing a receipt or completing a cash transaction, this dedicated printer will be used. In the Device Manager screen, look for all the printers on the network that are available. For 1:1 pairing, you can select your printer from here. ![1:1 Printer Topology setup in the POS app](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-commerce-retail-264-0-0-production-enus/17d647fb-8988-49fb-9add-c4f4cc79c9e4/retail/images/rt_cms_hardware_pos_app_1_1_printer.png) ## Configuring Printer Topology - 1:N Select a printer each time the POS app does any printer-related functionality at the merchant or register level in Point of Sale CMS. ![Note](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-commerce-retail-264-0-0-production-enus/17d647fb-8988-49fb-9add-c4f4cc79c9e4/images/icon_note.png) Note Note: 1:N configuration is not supported if connecting via Bluetooth. ### Merchant Level 1.
