Re: Canon LS-120pc

You need to have numlock on - even on a laptop. It's not very helpful like that because you typically can't use half the keyboard. Anyway once NumLock is on select PC or CAL. In CAL mode just type your calculation, get the result and press SEND to deliver the result to the PC, wherever you are typing. If you press PC mode the screen changes on the LS-120 and keypresses are sent through directly as you type them with no calculating done (like a numeric keypad).

Tax Function on Canon LS-121TS

The LS-100TS has tax keys. I suspect (for I cannot have access to a manual, just the online brochure by Canon) that you have to switch left to right or up-down one of the tax keys then you enter the tax percentage. and toggle back into position.

If that doesn't work repost.

To change the tax rate on the Canon MP11DX (and most others):

Slide the "GT" button to "RATE", enter your tax rate and hit the "TAX+" button. Once changed, slide the "GT" button back to the "ON" position.
