This is the standard product modify screen. A product can be selected
by using the scanner to input the bar-code, or by typing a few letters
of the product description and using the alpha lookup to find the
product, as with the sales screen.
Buttons at the base allow for printing a shelf edge label or a
product bar-code. If a receipt printer is available, the shelf edge
label is printed on this and is cut to the specified depth. Without
a receipt printer, the labels are printed on the default printer
by inserting a small piece of paper in the rear pass-through slot.
We found it convenient to use pages from a 'Jotter' pad. After printing,
the slip is trimmed to size with a small guillotine. Bar-codes are
always printed on the default printer.
