Casio HR-170RC Desktop Printing Calculator

The Casio HR-170RC is a desktop printing calculator that brings speed, clarity, and control to everyday number work. It features a display that shows 12 digits and is oversized for easy viewing, so you can glance up and confirm figures without squinting. When you hit the print key, the unit produces a crisp black and red tape at about 2 lines per second, making subtotals, credits, and debits stand out immediately. The keys are made of durable plastic and are spaced for comfort, which matters when you face long receipt tallies, inventory counts, or end-of-day reconciliations.

One of the most practical touches is the Check and Correct function. You can scroll back through as many as 150 steps, spot an error, fix it on the fly, and then reprint the corrected tape. That feature alone saves time and reduces the risk of missing a mistake that could throw off a whole ledger. A built-in cost, sell, and margin mode lets you move quickly from wholesale price to markup and retail figure, making the calculator handy on a sales counter or in a small-business office. The tape can also show the current time and date, giving every transaction a clear timestamp for later reference.

Power options keep the HR-170RC flexible. Pop in four AA batteries when you need to work away from an outlet, or plug in an optional AC adapter during longer sessions at your desk. The calculator accepts standard 2 1/4-inch paper rolls, so refills are easy to find. Decimal and rounding selectors, grand total mode, and independent memory round out a tool that fits naturally in accounting departments, retail back rooms, and home offices where reliable, hard-copy records still matter.
