A printer can print to paper with a narrow width while maintaining a print format with good legibility without changing the application program and printer driver installed on the host computer. The control method of a printer that prints based on print datasent from a host computerhas a step Sof extracting data attributes contained in the print dataand assigning the print datato data segment areas for each data attribute; a step of setting the data segment areas to specific printing areas based on the data attribute; an actual print data generating step (steps S, S, S, S, S) of converting the print dataassigned to the data segment areas to actual print data according to the data attributes; and a printing step Sof printing the actual print data in the printing areas.

Reduced printing width printer, printer control method, and operation control method

An electronic method for printing is disclosed, the method including receiving print data from a host computer, the print data including an indicator, wherein the print data does not include supplemental duplex or simplex printing settings, determining that the indicator is within the print data, analyzing the indicator to determine duplex or simplex printing, writing a first portion of the print data to a memory unit, writing a second portion of the print data to the memory unit, printing a first side of a paper according to the first portion of the print data, and printing a second side of the paper according to the second portion of the print data.

Printing device and control method for a printing device

A thermal printer and a control method for a thermal printer enable increasing throughput before a printing process starts by starting a duplex printing process without waiting to convert all print data into the front print buffer and back print buffer, enable executing a duplex printing process on a print medium without using a front print buffer and a separate back print buffer, and enable switching between simplex printing and duplex printing according to a specific command. The control method includes a step Sof receiving a printing process selection command specifying execution of a simplex printing process on a front sideof the print medium, a simplex printing process on a back sideof the print medium, a duplex printing process that prints on the front sideand the back side, and an identical front/back printing process that prints the same print data on the front sideand back side, a step Sof converting and buffering the print data, and a step Sof executing the printing process specified by the printing process selection command.

Printer and printer control method

An apparatus comprising a first detector for detecting if conveyed work that has passed or is passing a specific position is or is not present at a first position; a calculator for calculating a distance traveled by the conveyed work based on the specific position; and an evaluator that determines the conveyed work was removed if the first detector does not detect the conveyed work when the conveyed work is determined to be present at the first position based on the calculated traveled distance.
