Hi,
I am developing a dot-matrix printer driver in which i am printing raw text that is it is text only driver but my requirement is it should behave as text only driver in case of texts and when there will be an image in the document then it should print image also.
currently my driver printing raw text and skipping the image in the document.
Where i have to do changes in the driver to solve my purpose?
I am using WDK. You can refer tty sample for more clarification.
Please help me to sort out this issue.

Thanks in advance.

The text only driver does just that: it prints text only. It is intended for use with printers that do not print graphics, or to create a text file from a document.

If you want to print graphics you need to use a different driver. As you say you are developing one, you will need to use the printer's image commands to print images. These commands will vary from printer to printer (depending on whether the printer supports, PCL, PS, ESC/P, etc). If you write your own driver you will also have to accept that it will only work with compatible printers. And, some printers will not print even text with your driver (so-called GDI printers do not understand text)

Thanks for response.

Clarified a bit , but still confusion into the mind.

Is it possible my driver behaves as text as well as graphics depending on the data received from the document. Say, when text comes it behaves as raw / text printer and when image (bitmap/ jpeg etc.) comes it behaves as graphics printer.

Or in case of image any suggestion that I can implement into my driver?

Thanks in advance.

As I said in my first post, you need to send the printer the correct commands to interpret the data as graphics. What those commands are depends on the language the printer supports. For PCL printers the commands are character sequences starting with the ESC character (hex 1B). For details on PCL5 commands, try this link:
