These states are classified according to the state of the release lever, the presence or absence of roll paper in the paper transport path, and the presence or absence of a page break command. First, each state shown in the state transition diagram of FIG. 15, the transition condition from that state, and the state of the transition destination will be described.
- “Release lever closed and no paper” 2 210 indicates that release lever 15 is closed, roll paper CS is not placed in paper transport path 5, and host computer 15 The printer has not received a page break command that is a print instruction from 0.
- the state transits to the “release lever battle state 230 ′” ′.
- the state transits to the “release lever closed and paper waiting state” 220.
- “Release lever closed and paper waiting state” '220 indicates that the release lever 15 is closed and the roll paper CS is not placed in the paper transport path 5. It is in a state where a page break command has been received from the computer 150. In this “release lever closed and paper waiting state” 220, printing must be performed using roll paper.
- “Release lever state” 2300 indicates that the release lever 15 is in a leaping state and the roll paper CS is not placed in the paper transport path 5, and the host computer 150 is connected to the printer. -The device is in a state where it has not received a page separation command. In other words, in the “release state” 230, the roll paper CS is not placed in the paper transport path 5 because the release lever 15 is in a leaping state, and the page for which a print instruction is given. No delimiter command has been received.
- Release roll sensor 3.6 is set to release lever 15 when roll paper CS is placed in paper transport path 5 and release lever 15 is closed in 230.
- the TOF sensor 33a and the BOF sensor 27a are turned ON and the roll paper CS is detected, the roll paper CS is cueed and transited to the ⁇ Page separation command waiting state '' 240 I do.

- the “page break command waiting state” 240 is a state in which the release lever 15 is in the closed state and the roll paper CS is placed in the paper transport path 5, and the page break command is issued from the host computer 150. Is not received. That is, in the “page-separation command waiting state” 240, the page-separation command as a print instruction is not received, but the roll paper CS is located in the paper transport path 5 while being caught. It is in the state of being. In the “waiting for ⁇ page break command” state 240, the host When a page break command is received from the printer 150, the state transits to the “printable state” 260. In addition, when the release lever 15 is operated in the “page break command waiting state” 240 and the release lever 15 is in a bat state, the state transits to the “release state” 230. '
- “Release lever open and paper wait state” 250 indicates that the release lever 1 & is in the state where the roll paper CS is not placed in the paper transport path 5 and the host ⁇ The page separation command is being received. In the “release lever battle and paper waiting state” 250, since the page break command has been received, printing is possible when the roll paper CS is placed in the paper path 5.
- release lever 15 when the release lever 15 is closed without inserting the roll paper CS in “Release lever battle and paper waiting state” 250, the release lever sensor 36 confirms that the release lever 15 is closed. Then, both the TOF sensor 33a and the BOF sensor 27a are turned off, and the state transits to "release lever closed and paper waiting state” 220.

- the printable area corresponding to the page break command in the “printable state” 260 corresponds to the entire roll paper. Even if printing of a certain image data is completed and a print end command or a new page break command is received, the state does not change, and the “printable state” 2 6 Transitions to 0 by itself and no state transition is performed.
- the process starts from the “page break command waiting state” 240. If the roll paper CS has not been caught in the paper transport path 5 after performing the processing according to the flowchart shown in FIG. 12, the release lever is closed and there is no paper. To start? Then, from each state, the state changes to the printable state 260 by appropriately arranging the roll paper and transmitting the page break command to the printer main unit 1, and receiving the image data in that state. Thus, printing is performed.
