Casio HR-170RC Printing Calculator - Two-Color Desktop Print

Our review of the Casio HR-170RC finds it is a practical, no-nonsense printing calculator for small offices and shop counters that need a reliable paper record. The single biggest reason to buy is its combination of a fast two-color print mechanism and useful built-in functions like Cost/Sell/Margin and a 150-step check that make routine bookkeeping and profit checks quicker and less error-prone. It is not flashy, but it delivers clear, readable output and straightforward operation for everyday tasks.

Key Features

• Two-color printing: Prints numbers and negatives in two colors at up to 2.0 lines per second to make receipts and error spotting easier.
• 12-character display: A 1-line screen shows up to 12 characters so figures are easy to read before printing.
• Cost/Sell/Margin: Built-in cost, sell and margin functions let users compute profit and pricing without manual formulas.
• Check and correct: The check function lets you review and correct up to 150 steps so multi-step calculations can be audited and fixed.
• After Print reprint: After a correction, the After Print function makes it simple to reprint the corrected receipt for records or customers.
• Clock and calendar: Prints date and time on receipts to keep paper records organized by day.

Who It's For

The HR-170RC is aimed at small business owners, shop counters and office workers who need a compact desktop calculator that prints clear, two-color receipts for transactions and bookkeeping. Its portability and battery option also suit mobile vendors or temporary points of sale where plugging in is not convenient.

Those who need multi-line displays, advanced programmable functions, or networked POS integration should look elsewhere, as this model focuses on reliable printed records and straightforward arithmetic rather than complex automation or connectivity.
