Abstract: A printer enables determining the replacement status of a printer, thereby enabling forecasting problems specific to a printer location (such as a checkout lane) and problems specific to a business, and enabling easily devising a solution to the problems. A printer 40 disposed to a printer location has an interface 48 to which memory 34 associated with the printer location (lane n) is removably connected; and a printer replacement information writer that writes printer replacement information through the interface 48 to the memory 34 at a specific time.

Abstract: Based on characteristics of the font type, the results of printing by a previous printer and the results of printing by a replacement printer are made the same or nearly the same. The control unit 15 of the printer 10 receives control data including font type information specifying a font type, and character identification information specifying a character or string. When the font type specified by the font type information is a specific type of font, the control unit 15 adjusts the size of the font data of the character specified by the character identification information based on an adjustment value read from adjustment information data KY stored by a storage unit 16, and controls a print unit 17 to print the character based on the adjusted font data.

Abstract: A printer and printing control method to enable print data received from a host computer to be selectively deleted without modifying the host computer or application. A data receiving unit 100 receives print data from a host computer 40. A deletion line parameter unit 81 sets the number of deletion lines that are to be deleted from the received print data. A print data deletion unit 87 deletes the print data corresponding to the deletion lines set by the deletion line parameter unit 81. A printing unit 120 then prints a receipt using the actual (i.e., corrected) print data, which is the received print data remaining after deletion of the selected deletion lines by the print data deletion unit 87.

Abstract: A printing apparatus in which watermark data is stored and a printing control method that controls whether or not the watermark is to be printed on a receipt superimposed with specific print data received from a host apparatus. When it is determined that the watermark is not to be printed over the specific print data, a controller determines where on the receipt the specific print data is to be printed to avoid the watermark.

Abstract: A printing apparatus in which data representing a watermark is stored, printing system, and a printing control method that permits the watermark to be printed on a receipt superimposed with print data received from a host apparatus including a watermark printing avoidance control unit for avoiding printing the watermark on the print area of the receipt identified for printing specific print data contained in the received print data from the host apparatus.

Abstract: A printer enables selecting the process used for printing to the end of the print data when a no-paper state occurs during printing. The printer 1 has a resumption unit 37 that resumes the interrupted print job after a no-paper state is cleared, and a starting unit 39 that prints the print data from the beginning after a no-paper state is cleared. When a no-paper state occurs during printing, the resumption unit 37 or starting unit 39 that was set by the process content setting unit 32 operates. It is therefore possible to select the process for printing to the end after a no-paper state occurs without needing to modify the application program that runs on the external device 50 that sends the print data to the printer. Because the print data can be printed to the end regardless of which process is selected, it is also not necessary to resend the print data from the external device 50.
