Signature on F110 check printing

hi gurus,

We have problem with our AP check printing.

The printer has chip where our CFO's signature resides. And when you print the check from Production System, it prints the signature. But when you print the check from Development and Test system, it Prints an exclamation mark.

Now we have to move to the new printer, we are just changing the network cable to move from old printer to new printer.

And trying to print the signature from Production system to new printer but its still giving an exclamation mark.

New printer also has chip with CFO's signature.

Our Sapscript and Print Program both are copy of standard program and then added some code in there(customized), but in both i dont see any code where it differentiate between systems and prints the signature.

I am debugging only the customized code not the standard code.

Do you think signature printing (based on system) can be in standard code? or in SPRO settings? or in custom code (and i am missing that)? or in Printer setup or any other place which i could not think of???

Please help!! printer needs to be changed by next week.

Any suggestion would be helpful.

Thank You!!!
