If you have multiple printers or have a fax machine connected to your computer it is likely that a default printer has not been set. To assign a default printer, follow these steps:
1. Click Start -> Control Panel - > Printers and Faxes. You should see your printers listed.
2. Right click on the printer you wish to print from and select "Set as Default Printer."
If you have a default printer set and you still stay on "Sending to Printer" page, try to print the coupon again using a different Internet browser.
