The Zebra ZQ630 Plus is a rugged, portable mobile printer built to be carried on a belt or shoulder strap for field use — courier delivery confirmations, mobile retail receipts, or on-site labelling rather than a fixed desktop role. This configuration is set up for linered label stock (labels on a backing liner, as opposed to the linerless variant of the same printer) using a 0.75" core, with Bluetooth connectivity to pair with a handheld terminal or phone and English font support built in. "Group E" in the listing refers to a Zebra accessory/configuration grouping rather than a separate spec. It ships with a shoulder strap and belt clip, the standard carry accessories for a printer meant to move around a warehouse floor or delivery route all day rather than sit on a counter.
