I've never tried to print a price list from Express Invoice. We use Excel to do that because we can make it interactive and easier to read.
In looking at it, I think a way around it would be to utilize the inventory feature. If you have put in inventory amounts for each of the items, you can print out an inventory report. It lists each item that EI manages inventory for, the quantity in stock, and the value. The value is the price of the item, not the total value of the stock on hand. That report is printable.
Hope this helps!
