If I understand you correctly, you need to create a Custom Size form.
Custom Form
Control Panel> icon view > Devices and Printers>
Left-Click on your Printer one time to highlight>
Left-Click Print Server properties
HP How-to Document:
It is likely you will need to round up the size of your card -- as I recall, the custom form adjusts to within at least the tenth inch.
The margin can be controlled within the software you are using to submit the job to the printer.
For example, Word can be set to the Page Size (6x9) and the margins can be set to Custom to accomodate the 3/4 inch margin around the content.
