A printer base (3) and a printer with same, and a data printer for airplanes. The base comprises: a bearing component (10); a motor (19); a rotating wheel assembly, comprising a driving wheel (21) and a driven wheel (22); a rubber roll (25), connected to a rotating shaft (23) of the driven wheel and disposed at a top part of a printing head (4) of the printer; a tensioning assembly, comprising a sliding block (27), a guide rod (28), and a spring (29), wherein the spring is kept in a compressed state and applies a tensioning acting force on the sliding block all the time, the sliding block is capable of moving forward and backward along the guide rod when the spring is compressed or stretched, the sliding block is further provided with a tensioning wheel (5011), and a tensioning belt (24) is wound around the tensioning wheel and the tensioning belt is maintained in a tensioned state under tensioning action of the spring on the sliding block; and a paper shaft assembly (30), fixed between a first vertical mounting frame (11) and a second vertical mounting frame (16), horizontally suspended above a horizontal bearing frame (18) and used for mounting a printing paper scroll. The technical solution is advantageous to improving consistency and retainability of performance of the printer. |
