a platen roller that is provided at a position facing the thermal head, that pulls out, by being rotationally driven, one end of a roll sheet obtained by winding the label sheet in a roll shape, and that conveys the roll sheet to the thermal head; and a reciprocating control unit (configured to, when a print start instruction is received, cause a holding position of the label sheet sandwiched between the thermal head and the platen roller to reciprocate between a first position downstream in a conveyance direction of the print sheet and a second position upstream of the first position. ## Claims ### Claim 1 A printer apparatus, comprising: a print component configured to execute printing on a print sheet that includes a front surface as a print surface and a back surface as an adhesive layer and that does not include a liner over the adhesive layer; a conveyance component provided at a position facing the print component, that pulls out, by being rotationally driven, one end of a roll sheet obtained by winding the print sheet in a roll shape, and that conveys the roll sheet to the print component; and a reciprocating component configured to, when a print start instruction is received, cause a holding position of the print sheet sandwiched between the print component and the conveyance component to reciprocate between a first position downstream in a conveyance direction of the print sheet and a second position upstream of the first position in the conveyance direction. ### Claim 2 (depends on 1) The printer apparatus according to claim 1, wherein the first position is downstream of the holding position in the conveyance direction of the print sheet, and the second position is upstream of the holding position in the conveyance direction of the print sheet. ### Claim 3 (depends on 1) The printer apparatus according to claim 1, further comprising: a print start position moving component configured to move, to a print start position, the print sheet moved by the reciprocating component. ### Claim 4 (depends on 1) The printer apparatus according to claim 1, wherein the first position is downstream of the holding position in the conveyance direction of the print sheet, and the second position is a print start position. ### Claim 5 (depends on 1) The printer apparatus according to claim 1, further comprising: a standby position moving component configured to, after the printing is completed, convey a leading end of the print sheet to a standby position downstream in the conveyance direction of the print sheet. ### Claim 6 (depends on 1) The printer apparatus according to claim 1, further comprising: a cutter that cuts the print sheet discharged from a discharge port after printing is completed. ### Claim 7 (depends on 1) The printer apparatus according to claim 1, wherein the conveyance component comprises a platen roller. ### Claim 8 A label printer, comprising: a thermal print component configured to execute printing on a print sheet that includes a front surface as a print surface and a back surface as an adhesive layer and that does not include a liner over the adhesive layer; a conveyance component provided at a position facing the thermal print component, that pulls out, by being rotationally driven, one end of a roll sheet obtained by winding the print sheet in a roll shape, and that conveys the roll sheet to the thermal print component; and a reciprocating component configured to, when a print start instruction is received, cause a holding position of the print sheet sandwiched between the thermal print component and the conveyance component to reciprocate between a first position downstream in a conveyance direction of the print sheet and a second position upstream of the first position in the conveyance direction. ### Claim 9 (depends on 8) The label printer according to claim 8, wherein the first position is downstream of the holding position in the conveyance direction of the print sheet, and the second position is upstream of the holding position in the conveyance direction of the print sheet. ### Claim 10 (depends on 8) The label printer according to claim 8, further comprising: a print start position moving component configured to move, to a print start position, the print sheet moved by the reciprocating component. ### Claim 11 (depends on 8) The label printer according to claim 8, wherein the first position is downstream of the holding position in the conveyance direction of the print sheet, and the second position is a print start position. ### Claim 12 (depends on 8) The label printer according to claim 8, further comprising: a standby position moving component configured to, after the printing is completed, convey a leading end of the print sheet to a standby position downstream in the conveyance direction of the print sheet. ### Claim 13 (depends on 8) The label printer according to claim 8, further comprising: a cutter that cuts the print sheet discharged from a discharge port after printing is completed. ### Claim 14 (depends on 8) The label printer according to claim 8, wherein the conveyance component comprises a platen roller. ### Claim 15 A method of printing a print sheet that includes a front surface as a print surface and a back surface as an adhesive layer and that does not include a liner over the adhesive layer, while minimizing jamming, comprising: printing on the print sheet; pulling out, by rotationally driving a conveyance component provided at a position facing a print component, one end of a roll sheet obtained by winding the print sheet in a roll shape, and conveying the roll sheet to the print component; and when a print start instruction is received, causing a holding position of the print sheet sandwiched between the print component and a conveyance component to reciprocate between a first position downstream in a conveyance direction of the print sheet and a second position upstream of the first position in the conveyance direction. ### Claim 16 (depends on 15) The method according to claim 15, wherein the first position is downstream of the holding position in the conveyance direction of the print sheet, and the second position is upstream of the holding position in the conveyance direction of the print sheet. ### Claim 17 (depends on 15) The method according to claim 15, further comprising: moving, to a print start position, the print sheet moved by the reciprocating component. ### Claim 18 (depends on 15) The method according to claim 15, wherein the first position is downstream of the holding position in the conveyance direction of the print sheet, and the second position is a print start position. ### Claim 19 (depends on 15) The method according to claim 15, further comprising: after the printing is completed, conveying a leading end of the print sheet to a standby position downstream in the conveyance direction of the print sheet. ### Claim 20 (depends on 15) The method according to claim 15, further comprising: cutting the print sheet discharged from a discharge port after printing is completed.
