Abstract:
1. A printer control device comprising: a first port and a second port, each of which receives a print data from an external device; a receiving buffer used by the first port and the second port to temporarily store the print data; a storage used by the first port and the second port to store the print data received by the first port and the second port; an image creator which creates image data based on the print data from the external device; and a controller which judges whether the image creator is creating the image data based on previously received print data, when the first port or the second port receives new print data from the external device; wherein the controller controls storing of the new print data in the receiving buffer when the image creator is not creating the image data, and stores the new print data in the storage when the image creator is creating the image data; wherein the controller controls the image creator to create the image data based on the print data stored in the storage; wherein before the image creator completes creating the image data based on the print data, the controller judges whether another print data is stored in the storage, and controls the image creator to create the image data based on the stored data in case the another print data is stored in the storage; and wherein, while the controller stores the print data received by the first port or the second port in the storage, the controller starts reading out the print data stored in the storage and the image creator starts creating the image data based on the print data before the completion of storing the print data in the storage.
