The Canon P170-DH is a solid machine — right up to the morning the ink roller fades, the roll runs out mid-total, or it simply stops. Here is how to keep working exactly the same way on the PC — key for key — and what it saves you in paper and ink roller every year.

Everything carries over, key for key

The tape, blind touch typing, the key sound, Grand Total, the memory and the tax key — they all work the way they do on the Canon P170-DH. The full switch guide shows every key and where it lands in DeskCalc, what stays the same, and what a paper tape simply cannot do.

What the Canon P170-DH costs you every year

A machine on the desk does not feel like a running cost, because it is paid in small amounts. Here is the same calculation our ROI sheet uses, with this model’s own supplies.

Item Assumption Per year
Paper rolls (2¼″) 6 rolls at $0.99 $5.94
Ink roller (Canon CP-13) one per year $3.00
Electricity 9 W, 8 h/day, 5 days, 48 weeks — 17.28 kWh at $0.15 $2.59
Running costs $11.53
Plus the machine itself spread over 8 years $80.00
Total over 8 years $172.24

Running costs are rounded to the cent; the eight-year total is calculated from the unrounded figures.

Questions about replacing the Canon P170-DH

Can DeskCalc really replace a Canon P170-DH?

Yes. DeskCalc is a Windows program that works the way the Canon P170-DH does — a running tape you read as you type, blind touch-typing on the numeric keypad, Grand Total, the memory keys and a sales-tax key. Everything carries over key for key; what goes away is the printing, the supplies and the wear. The full switch guide shows where every key lands.

Do I still have to buy the Ink roller (Canon CP-13) and paper rolls?

No. DeskCalc’s tape is on the screen, not on paper, so there is no ink roller (Canon CP-13) and no paper roll to replace — ever. That recurring cost, about $11.53 a year to keep a Canon P170-DH running, is exactly what the switch removes.

Which keys are different from the Canon P170-DH?

Almost none. +, −, ×, ÷, %, Grand Total, item count and the memory keys all map straight across. The one thing DeskCalc has no dedicated key for is Cost / Sell / Margin — and you won’t miss it: a markup is one labelled line on the tape (cost × 1.30), a margin is cost ÷ 0.80.

Does DeskCalc need an account or an internet connection?

No. It runs entirely on your PC — no account, no cloud, no connection — and what you calculate stays on your computer. It installs on Windows 10, 11 and Server and is a 10 MB download.

Can I get the tape into Word or Excel?

Yes. Copy the tape and paste it into Word, Excel or a PDF — with the columns, the labels and the negative amounts in red. That is the part a paper strip from the Canon P170-DH could never do.

Can I try it before I give up the Canon P170-DH?

Yes. The trial runs 31 days with no limits and no account — long enough for a full month-end, the only test that matters. A single licence is $29.95.

Try it before the Canon P170-DH dies

The trial runs 31 days with no limits and no account. That is long enough for a full month-end — which is the only test that matters.
