QUESTION: Dear ZZ

Is it technically feasible to reengineer the Typewriter device which allows different colours to be printed on the paper.

Example

Hello word to be printed.

The characters H,e,l,l,o keys before striking the color ink are selected with the red color by the Typewriter user.

Thanks
Prashant

ANSWER: What?  Typewriter?  They are virtually non-existent at least here in the USA.  There are a few professional applications where forms must be filled with mechanical type but the typewriter has essentially been replaced with a printer and word processing program on a computer or electronic processing machine.

In any event, it would be very difficult to design an electro-mechanical typewriter to give different colors within the same word.  Not saying it can't be done by I have not seen it executed.  There are two color ribbons available for use with typewriter and if the rotary head were made available with the same font on each layer of the ball you could accomplish such facility using the IBM selectric type machine.

Does this help?

QUESTION: Dear ZZ

Thanks.

1 Can Embedded software build within the Typewriter device help in this regard?.

2 New color ink pen keys are designed on the Typewriter. Examples Red,Blue,Green etc.

The character H is selected with the Red color ink pen key pressed together.

Is this possible?.

Thanks
Prashant

Answer
What you are describing with ink contained within the key striker is called a color printer.

There are two kinds of printers extant
Those that connect to a computer and those that have software self contained.

So, I think what you want is a color printer which, by the way, costs less than a typewriter.

Good luck .
