Hello sa3a
unless a member here has psychic abilities, it will be next to impossible to advise you what the problem is based on the info you provided.
Having said that, allow me to ask if you have seen and acted on the list of questions from the 7/29/2012 @ 3:34 am that you were given in your how can i print strings in red color via CP340 ? thread?
If so, what did you find (the answers to them may help you with this problem)?
Cheers

hi fritz, i'm really embarrassed,after your advises i didn't find anything to solve my problem, you know i was disappointed,and i found another problem insted, i can't print with P_PRINT even with black color anymore,i guess after enter false commands to print in red color, my PLC or my SIMATIC MANAGER
got problem with P_PRINT function,how? when you set the REQUEST entry of P_PRINT it must print the DATA BLOCK that you assigned to this function certainly, if not it must put an error code in it's output,but after do this sequences there is nothing i mean the printer and the PLC doesn't show any reaction to my command,i want to know how can i resolve this problem ?!! thanks.

Hello sa3a
the best (and possible only) advice I can give you is to rool back to the program backup that worked.
Should you not have the original backup anymore, you'd need to manually retrace your steps and "undo" the changes that you made.
Alternatively, I suggest you get in touch with your nearest Siemens Solution Partner and asked them to come to your site and give you a helping (chargeable) hand.
I hope this helps
Cheers
