Applying for a job in a bookstore, and one requirement is - Must be proficient in operating a 10-key calculator.
Is that the same as the numeric keypad on the right side of the
computer keyboard? If so, I'm reasonably accurate on it but not super

I am not trying to make a backup. I want to be able to copy a program I
already manually typed into the calculator to edit on a computer, and
then transfer back the edited version to the calculator.

The manual for the Canon P1-DHV is online at http://www.usa.canon.com/app/pdf/calculator/P1-DHV_G_USA_HWB.pdf>.
When the display shows "5/4", the calculator is doing 5/4 rounding which means: 5 or above round up, 4 or below round down. To control rounding press the "5/4" key.
When the display shows "E" the calculator could not complete a calculation. It can be because of dividing by 0, or because the total exceeded 1 trillion, or because the operator entered calculations faster than the calculator could complete them. Press the CI/C key to clear it.
I can't explain why you are not getting a total on the tape. Try the following example from the manual exactly as shown, and let me know if your tape shows the total.
Clear the calculator (press [CI/C])
Choose 5/4 rounding (press [5/4] until "5/4" displays)
Choose add mode (press [DEC] until "A" displays)
Choose cost-sell-margin mode (press [B-T] until "B" displays)
Turn printer on (press [PRINT] until "PRINT" displays)
OFF • P P•IC ON POWER SWITCH; PRINT / ITEM COUNT MODE SELECTOR: "OFF": Power OFF "•": Power ON. Set to the non print mode. "P": Power ON. Set to the print mode. "P•IC": Power ON. Set to the print and item count mode. 1) For addition or subtraction, each time is pressed, 1 is added to the item counter, and each time is pressed, 1 is subtracted. • The count is printed when the calculated result is obtained. • Pressing of , clears the counter. 2) When the grand total/rate setting mode selector is in the ON position (GT), the counter will count the number of times that the calculation results have been stored in the grand total memory. To print and clear the count, press the key. 3) The memory item counter will count the number of times that the key has been pressed in the addition. Note: • Each time the key is used in the subtraction, 1 will be subtracted from the count. • The count is printed when the memory is recalled. • Pressing of the key clears the counter. Note: The counter has a maximum capacity of 3 digits (up to ±999). If the count exceeds the maximum, the counter will recount from zero.
Hi....by looking at the date you posted this question, you may have already found the answer, but just in case you haven't......the procedure for adding and subtracting on these calculators is completely opposite of a regular calculator. On a regular calculator, you would input 4 - 4 = 0. On these type of calculators, a number's positive or negative status is keyed in AFTER the number, instead of before it. Therefore, you input 4 + 4 - (notice you DO NOT input = at the end, but if you are in print mode, you will need to hit your total key, which looks like an asterisk, where the = would normally be, in order for the final value of your calculations to print on the paper tape.
Multiplication and division equations are done exactly as they are on a regular calculator....4 x 4 = 16.
Hope this helps. If you have your owners manual, it should also give you some examples of how to perform calculations with your calculator.
Assuming that you have the correct print wheel fitted and that the typewriter is on standard key board setting then I would look at anything that might be interfering with the rotation of the print wheel. First, remove the print wheel and check that none of the character arms are distorted,then look at how the correction tape is fitted. If this tape is not fitted correctly it could be interfering with the rotation of the print wheel.
