Abstract: A packaging system includes, in addition to a packaging machine of a known form-fill-seal type and a printer for printing on a bag-making film, a packaging condition memory which stores packaging conditions for operating the packaging machine, a print data memory which stores print data for operating the printer, and a correlation data memory which stores the correlation data between the packaging conditions and the print data. If a packaging condition is selected through an input device, not only is the packaging machine operated under the specified condition but also the printer is operated by the data which correspond to the selected packaging condition according to the correlation data stored in the correlation data memory.
