[FIX] point_sale: Width of reciept is calculated for smaller devices

When user tries to print a receipt from a small device, sometimes receipt
is cropped on the right side. This happens because unlike height, receipt
width is not calculated, instead it is equal to the width of the receipt div.

The width of the receipt is equal to the outer width of the receipt instead of div
and the receipts are not cropped anymore.
