When a purchase goes through on the VM webpage how do I get VM invoice to send the invoice automatically?

What plugin do I use or how do I setup CRON job?

I edited the the invoice to how I want it to be but when I buy something through VM the standard Invoice and email are sent but not the one from VM invoice.

How do I disable the standard email and Invoice and let the VM invoice and email send automatically instead?

Thanks this worked.

I figured this out you have to go to global configuration in VM invoice and disable the "cache pdf" option for the language override to work.

How do I remove the footer?

I'm trying to use the language override to translate the invoice but it doesn't seem to work. My site is set to the Danish language but I translated the constant in both the English and the Danish language but it doesn't seem to make any difference.

To clarify I will give you all the details. I take this constant: COM_VMINVOICE_QTY which is by default: "Qty."

I use language override in Danish to change it to "mængde" and then I change it to "mængde" in English as well but when I try it out by clicking on of the pdf's under Invoice/Order Management in the Artio VM Invoice it still displays "QTY"

Please tell me how to fix this.
