Printing apparatus, pos system and printing apparatus control method

Abstract

A printing apparatus and method for printing receipts and for controlling the cutting of each receipt in succession from a recording medium such as print paper at an appropriate position determined from the print data received from a host computer. The printing apparatusprints first print data representing transaction information with a paper cut command appended thereto and second print data representing additional information from print data received from a host computer. A first control unitprints the first print data and delays executing the paper cut command added to the first print data when first print data is received from the host computer. When print data is received while execution of the paper cut command is delayed, a print data detection unitdetermines the type of print data received based on the presence or absence of an identifier in the received print data. If the received print data is recognized as second print data, a second control unitprints the received second print data and then executes the paper cut command. If the received print data is determined not to be second print data, the second control unitexecutes the paper cut command before printing the received print data.
