Abstract
Abstract A label printer of the type including two printing devices which can issue a label and record paper at locations near to each other with printed faces thereof directed to the front is realized by a specific arrangement of two printing devices and two supply devices without increasing the overall size of the printer. The label printer comprises a first printing device including a first print head mounted for up and down pivotal motion and for engagement with an upper face of a first platen, a second printing device located within a same vertical volume below the first printing device and including a second print head mounted for up and down pivotal motion and for engagement with a lower face of a second platen, a first supply means located behind the first printing device for holding a backing sheet in the form of a roll to which a large number of labels are applied and for supplying the backing sheet to the first printing device with the labels directed upwardly, and a second supply means for holding elongated record paper in the form of a roll with a printing face thereof directed outwardly and for supplying the record paper to the second printing device with the printing face of the record paper directed downwardly.
