The Sharp EL-2630 printing calculator is an indispensable tool for both home and office. The EL-2630 displays an extra-large 12-digit LCD display for better viewing, and two-color ribbon printing (positive numbers in black, negative numbers in red) is enabled at about 4.8 lines per second on standard paper rolls. The EL-2630 has four-key memory (memory plus, memory minus, and recall/clear) and special functions keys including grand total, adding mode, constant, double zero key, mark-up/profit-margin key, item counter, and rounding settings. Decimal settings are adjustable from floating to fixed decimal places (6-3-2-1-0). A calendar/clock function displays and prints the date and time.
