How to print

[Viraj Gohil]

Hii.
Can I send my present output screen for print.
I have made a billing program so if I can send it to print then it will be perfect.. thankyou

you could pipe it to lpr

or use CUPS http://stackoverflow.com/questions/14518004/linux-cups-printing-example-tutorial

Alternatively you can try this:

FILE *stdprn;
stdprn = fopen("prn","wb");
fprintf(stdprn,"This should appear on the printer");
fclose(stdprn);

My printer is not working so I can't test.
