Modified receipt issue

Since I do not like the sample receipt that has way too many spaces, I downloaded the 40 column no space from Customersource. The previous original receipt is perfect (uses the width of the paper, everything centred etc) but too many spaces. I started using the one that I downloaded and the spaces are still there and it crammes the text not using the whole width and the message under the barcode is no longer centred. I checked the properties and the are the same... ideas? -Manny
