What Is a Printing Calculator?
A printing calculator — also called an adding machine or calculator with tape — is a calculator that records every number and operation on a paper roll. Accountants, bookkeepers, and auditors have used these machines for over a century because the tape provides a verifiable record of every keystroke. If a total looks wrong, you simply scan the tape to find the mistake.
Why Accountants Love the Tape
In double-entry bookkeeping, every journal entry must balance. The tape lets you add up debits on one run and credits on another, then compare the two totals. In reconciliation, you enter each bank statement item and check whether the running total matches the closing balance. The tape is your audit trail — it proves the math is right.
Features of This Calculator
Paper tape: Every operation scrolls upward like a receipt roll. Numbers are right-aligned and the operation symbol (+, −, ×, ÷) appears on the right edge. Memory: M+ adds the displayed value to memory, M− subtracts it, MR recalls it, MC clears it. Grand total: The GT button sums every subtotal you have computed with = during the session — useful for totaling multiple invoices or expense categories. Tax: Set your local tax rate and press +Tax or −Tax to add or remove tax from the current value.

Frequently Asked Questions
What is a calculator with tape?
A calculator with tape (or printing calculator) records every number and operation on a scrolling paper-like strip, just like the physical adding machines used in accounting. You can review, print, copy, or download the tape.
What is the Grand Total (GT) button?
The GT button sums every subtotal you have computed with the = button during your session. It is useful for adding up several separate calculations — for example, totaling invoices from different vendors.
How do the memory buttons work?
M+ adds the displayed number to memory, M- subtracts it from memory, MR recalls the stored memory value to the display, and MC clears the memory to zero.

How does the tax button work?
Set your tax rate in the Tax Rate field, then press +Tax to add tax to the current display value, or -Tax to subtract tax. The tax amount and new total appear on the tape.
