Altering .ai format to .cdr format

I am making design intended to corporate pamphlet. For this purpose I am using ILLUSTRATOR software. However in the printing press it is facing difficulty. Only the cdr format is accepted. Give me the hints to do it.

Hi,

CDR is different program, called Corel Draw - you'd need that software to make the file.

However, very bad for printers only to accept this file - they should be versatile and it's unusual that they can't accept an Illustrator file.

I think you should talk to the printer about alternatives, like a PDF for example.
