Printing on-line can have its challenges. Are you able to find a "Printer Friendly" version of the receipt?
Another option is to use a tool that I find very helpful. That is the Snipping Tool available on Windows Vista and newer versions of Windows. You can find it under Start | All Programs | Accessories | Snipping Tool. Once you open it, the monitor screen will turn hazy. You can put the cursor in the top left corner of the item you want to print, hold the left click button down until you reach the bottom right corner and let go of the button. You can then save and print the item you snipped.
