How to put the evaluated result in a text cell?

Question

If I use the function Print, the result is not in a text cell. So I wonder If there's a function that I can use to put behind the function Print, to make the evaluated result be placed in a text cell?

Here's the testing code!

1 + x^2 + x^4 /. x^p_ -> f[p] // Print

CellPrint[TextCell[1 + x^2 + x^4 /. x^p_ -> f[p], "Text"]]

If you wish to print into plain text cells, you have the following possibilities:

Instead of Printing into usual StandardForm Cell where the parsing and 2D formatting take significant processor's time you can print into plain text Cells:
```
CellPrint[Cell["stuff=" <> ToString[stuff]]]
```
Upon printing, you can assign the usual "Print", "Text", "Output" or another style to such a cell without changing its rendering from plain text:
```
CellPrint[Cell["stuff=" <> ToString[stuff], "Text"]]
```
The plain text rendering is determined by the fact that the Cell[...] object contains a simple String as the first argument and not a BoxData object.
Instead of printing into separate cells you can append the output into the same plain text Cell as described here:
```
stuff := RandomReal[];
Do[WriteString["stdout", "stuff=" <> ToString[stuff], "\n"], {10}]
```
This works extremely fast.

Here "stdout" is the name of the standard output stream. You can get the corresponding stream object with Streams["stdout"]. The standard output channel is $Output, which by default sends everything to "stdout". You can read more about them in this tutorial.

Your answer is really informative, which is more than what I expected, really instructive! – Lawrence Dec 23 '21 at 10:44
WriteString[channel,expr1,expr2], so the "stdout" means the channel? Actually, I don't know what is channel. Can you give some words about it? – Lawrence Dec 23 '21 at 10:46
