Hi all,
I have a problem with my POS program. I have printed a receipt through
/dev/lp0. It works.
But, when I want to execute a cut paper command, an error occurs. It says that
/dev/lp0 is busy.
I know that the printer is still printing when I execute a cut paper command.
So, how to handle this error?
I think, the solution is I have to execute a cut paper command after the
printer stop printing. But, I don't understand the code.
So, how the codes??? Help me please...
Thanks for your help...
