Printing device with means for conveying paper A printing device (10) comprises a lower part (12) and an upper part (14) that is mounted on said lower part (12) such that it can pivot about a pivot axis (16). A print head (18) and a holding trough. (62) for a recording medium supply roll (64) are arranged in the lower part (12) , and a conveying device (24, 30) for a recording medium (66), and a print backing support (36) spatially associated with the print head (18) are arranged in the upper part (14). The upper part (14) has two side walls (42) which laterally enclose a recording medium supply roll (64) put into the holding trough (62). The invention is characterized in that the print backing support (36) is planar in the printing area (70) of the print head (18), the conveying device comprises a pair of conveyor rollers (24) that are aligned parallel with the print backing support (36) and can be driven by a motor, and a tautening device (30) for the recording medium (66), and in that the pivot axis (16) is located underneath the print backing support (36).
A printing device (10) comprising a lower part (12) and an upper part (14) that is attached to said lower part (12), an imaging device (18) and a holding trough (62) for a recording medium supply roll (64) being arranged in the lower part (12), and a conveying device for a recording medium (66), and a print backing support (36) extending over a printing area (70) and spatially associated with the imaging device (18) being arranged in the upper part (14), the upper part (14) having two side walls (42) which laterally enclose a recording medium supply roll (64) put into the holding trough (62), and the upper part (14) being capable of pivoting about a pivot axis (16), between an opening position that opens the holding trough (62) and a printing position, in which the print backing support (36) is opposite the imaging device (18), characterized in that the imaging device is a serial-character or serial-column print head (18) which can be displaced in the direction of a line of print, the print backing support (36) is planar in the printing area (70) of the print head (18), the conveying device comprises a first pair of conveyor rollers (24) that are aligned parallel to the printing area (70) and can be driven by a motor, the first pair of conveyor rollers (24), as viewed in the conveying direction of the recording medium (66), being arranged upstream of the print backing support (36), and a tautening device for the recording medium (66), the tautening device comprising a second pair of conveyor rollers (30) driven at the same time as the first pair of conveyor rollers (24) arranged downstream of the print backing support (36), the second pair of conveyor rollers (30) being driven at a slightly greater conveying speed than the first pair of conveyor rollers (24) and having a coefficient of friction that is lower than the first pair of conveying rollers (24), and in that, as viewed in the direction of a line of print, a parking area (72) for the print head is arranged beside the printing area (70).
A printing device (10) comprising a lower part (12) and an upper part (14) that is attached to said lower part (12), an imaging device (18) and a holding trough (62) for a recording medium supply roll (64) being arranged in the lower part (12), and a conveying device for a recording medium (66), and a print backing support (36) extending over a printing area (70) and spatially associated with the imaging device. (18) being arranged in the upper part (14), the upper part (14) having two side walls (42) which laterally enclose a recording medium supply roll (64) put into the holding trough (62), and the upper part (14) being capable of pivoting about a pivot axis (16), between an opening position that opens the holding trough (62) and a printing position, in which the print backing support (36) is opposite the imaging device (18), characterized in that the imaging device is a serial-character or serial-column print head (18) which can be displaced in the direction of a line of print, the print backing support (36) is planar in the printing area (70) of the print head (18), the conveying device comprises a first pair of conveyor rollers (24) that, are aligned parallel to the printing area (70) and can be driven by a motor, the first pair of conveyor rollers (24), as viewed in the conveying direction of the recording medium (66), being arranged upstream of the print backing support (36), and a tautening device for the recording medium (66), the tautening device comprising a second pair of conveyor rollers (30) driven at the same time as the first pair of conveyor rollers (24) arranged downstream of the print backing support (36), the second pair of conveyor rollers (30) being driven at a slightly greater conveying speed than the first pair of conveyor rollers (24) and having a coefficient of friction that is lower than the first pair of conveying rollers (24), and in that, as viewed in the direction of a line of print, a parking area (72) for the print head is arranged beside the printing area (70), the first pair of conveyor rollers (24) or else the first pair of conveyor rollers (24) and the tautening device being formed by a driven roller (38;
