A printer, which is especially adapted for printing a bar code on label paper has a housing having a front panel with some operation buttons and a winding drawer having a protruding label table. The printer prints a bar code and alphanumeric numerals on a label which is fed to the label table for then being applied to goods. The printer also can be connected to an external computer or the like for obtaining the information to be printed on the label. The printer also has an internal processor and a memory for maintaining certain necessary information. The winding drawer has a winding roller and a deflection roller on a pivotable operation lever. The deflection roller deflects ground paper of the label paper over a dispenser edge in a first position of the operation lever, so that a label formerly on the ground paper is delivered straight ahead while the ground paper is deflected downwards to the winding roller operation. The lever and deflection roller also may be pivoted forwards to a second position, whereupon the ground paper including the labels can be delivered straight forwards as a long strip of labels maintained on the ground paper. By pulling out the winding drawer to an extended position and pivoting the operation lever and deflection roller to the second position, the labels on the ground paper also may be wound on the winding roller for later use. The printer also has one or several printing heads which are pivotable about 90 DEG for cleaning printing points thereof. The printing heads are easily exchangeable by loosening only two screws. |
