Shell Programming and Scripting

Hello!!!
I am using shell script that print some formated text on the screen (example)
========
hello I am ...
========

Is it possible to print this information to the printer exactly as I see it on the screen???

How can e answer such question ,since we dont know what the script does!
It helps also to know what OS and version we are dealing with, and in your case what type of spooler is used (network? CUPS? BSD? AIX? etc...)

Code:

echo -e "\033[0;31m===============================\033[0m"
echo -e "\033[1;35mHeader!!!\033[0m"
echo -e "\033[0;31m===============================\033[0m"
echo -e "\033[0;33m HELLO      WORLD\033[0m    "
echo -e "\033[0;31m===============================\033[0m"

Ah, you want to print ANSI color escape sequences? No, it can't, you'll need to convert it somehow.

What languages can your printer understand? Converting that to raw postscript may be difficult since postscript's quite complex. Converting it to HP PCL language, not as hard: PCL uses escape sequences too, albeit totally different ones, to do things like change locations, fonts, styles, and input modes.

If you can print this file raw and see a checkerboard, your printer understands PCL.

See here for a simple introduction.

is it possible to print screen to the printer???

You can take your screen to the scanner and scan it....
But seriously....... could you elaborate on what you're after....

What, like a text screenshot?

The answer depends on what your system is. Please explain in detail what terminal, software, and OS you're using.
