How to interface a printer using arduino?

Which printer? What does the overused "interface" mean?

Is it possible to control its printing using the usb cable?

Certainly. The printer is a USB slave. The Arduino is a USB slave, too. When there is no USB master around, the slaves just sit around and drink beer.

To preserve the beer supply, you need a USB Host shield, and you need to write some USB driver software.

Thanks sir.

Is arduino has an USB driver software for an inkjet printer? What are the libraries needed? And do you have an example codes?

Is arduino has an USB driver software for an inkjet printer?

No, of course not. The USB Host shield may come with a library, or a link to one. That library, or the authors of the library, may have developed such a driver (though I doubt it).

What are the libraries needed?

To do what?

And do you have an example codes?

        // Determine how many rows of data there are
        public int GetNumberOfPersons()
        {
            if (personTable == null)
                personTable = personAdapter.GetData();

            int personCount = personTable.Rows.Count;
            return personCount;
        }

This is an example of a web service function for getting the number of rows in the Person table in the database.

Hope that helps.
