A printing system includes a printing device, a platen roller, a controller, and an interface. The printing device includes a thermal head, a ribbon drive source, and a head drive source. When receiving a print command, the controller executes head movement control for moving the thermal head and ribbon acceleration control for accelerating a transport speed of an ink ribbon to a target speed. After completion of the head movement control and the ribbon acceleration control, the controller is configured to control the thermal head to perform printing on the print medium. At least before receiving the print command, the controller is configured to determine a printable distance over which the print medium is transported from the reception of the print command till the completion of the head movement control and the ribbon acceleration control and outputs the determined printable distance through the interface.

The present invention relates to a portable sublimation printer capable of simultaneously controlling up/down of a platen roller of a portable thermal sublimation printer and up/down of a printing medium pickup roller with a rack and pinion mechanism. A portable sublimation printer having a small thickness and a light weight to a rack apparatus of a portable sublimation printer is provided.

A printer includes a holder configured to house rolled recording paper, a cover that is attached to the holder to be openable and closable relative to the holder, and a contact part that is attached to the cover and configured to contact the recording paper. The contact part is configured such that the contact part substantially point-contacts the recording paper, and positions on the contact part contacting the recording paper change as the recording paper is unrolled.

A printing device for printing on a label sheet includes a first print head to perform printing on a first side of a label sheet being conveyed along a conveyance path. The label sheet is interposed between the first print head and a first roller. A second print head is upstream of the first print head and performs printing on a second side of the label sheet. A second roller is adjacent the second print head across the conveyance path. A cutter is downstream of the first print head to cut off a first portion of the label sheet. A processor is configured to cause the label sheet to be conveyed in a second direction after the first portion is cut off from the sheet so that the cut end of the sheet reaches the first print head.

A thermal printer comprises a sheet conveyance mechanism configured to convey a sheet formed by attaching labels on a mount; a ribbon conveyance mechanism configured to convey a ribbon; a thermal head configured to heat the ribbon to carry out printing of printing data on the sheet contacted with the ribbon; and a head moving mechanism configured to control the thermal head if a non-printing area is longer than a first distance based on the printing data to separate the ribbon from the sheet; wherein the ribbon conveyance mechanism stops the conveyance of the ribbon if the non-printing area is longer than the first distance; and the sheet conveyance mechanism controls, if the non-printing area is longer than the first distance, the sheet conveyance speed to a second speed slower than a first speed applied in a case of conveying a printing area.
