In the physical layer standards (IrDA-SIR), the infrared signal are established.
2.2 720 dpi Printing/Smoothing Feature 2.2.1 Canon extension mode In Canon extension mode, the printer driver creates 720 dpi data for the horizontal axis and sends it to the printer, allowing the printer to archive high-quality printing. With a black BJ cartridge installed, the printer driver smoothes the printed character's edges to 720 dpi along the horizontal axis.
Part 4: Technical Reference BJC-50 2.3 Printing Modes Depending on the cartridge installed, the medium, the printing mode, the resolution, the print data, etc., the printer varies the carriage movement, bubble jet head driving frequency, etc., to attain high-quality printing without any bleeding or shifting in the printout.
Part 4: Technical Reference BJC-50 2.4 Optimum Printing Direction Control To prevent vertical misalignment of the printed characters, etc., when print data is printed continuously in the direction of the paper feeding direction, printing is executed with the carriage moving from only one direction. However, when printing in the paper feed direction is not continuous, since vertical misalignment is not so noticeable, the printing direction is alternated so that printing is also executed from the opposite carriage direction.
Part 4: Technical Reference BJC-50 2.6 Lithium Ion Battery Recharging 2.6.1 Switching to recharge mode The lithium ion battery must always be installed in the printer as the recharging circuit for the battery is inside the printer.
