Print invoice from vb6 with crystal report 8.5

Dear Experts,
I developed an application with vb6 and right now, im using crystal report 8.5 for all the reporting needs and even creating invoices. However, my client wants the application to print invoices without first going into the crystal report screen. Coz rite now, whenever i call print invoice, my app will take the client to the crystal report screen and then he can print the invoice from there. Is there a way to print without first showing the report? Thanks in advance for the advice experts...
