Printer, and method for replacing printing head of printer

A printer configured to be switched between (i) a peeling issuing mode, in which labels that are releasably attached to a liner of a print medium are issued after being peeled from the liner, and (ii) a continuous issuing mode, in which labels that are releasably attached to the liner of the print medium are issued without being peeled from the liner, the printer comprising:

• a feed roller configured to feed the print medium;
• a print head configured to pinch the print medium with the feed roller and to print on the print medium;
• and
• a biasing member configured to bias the print head in a first direction toward the feed roller;
• and
• a peeling unit configured to hold a peeling roller that faces the feed roller when the printer is in the peeling issuing mode, the peeling unit being movable between (i) a closed position, at which the peeling unit at least partly covers the print head, and (ii) an open position, at which the peeling unit does not cover the print head;
• wherein:
• the print head is movable in the first direction between (i) a first position, at which the print head can be removed when moved in a second direction, and (ii) a second position, at which the print head cannot be removed when moved in the second direction;
• and
• when the peeling unit is at the open position and the print head is at the first position, space for allowing mounting and removing the print head is formed.
