Anybody experience with increasing barcode size on form?

Question

We are printing an SU Label form with a barcode. The SU Label is a WM sapscript form. I've been trying to size up the barcode as large as possible to get our scanner to read it at least 30 feet. In SE73, my print control is currently set to:
\e(s4p100h220v55,165b55,165s24704T
This gets us to around 20 feet before it can no longer be scanned. I'm wondering if anybody has insight into anything that can be done to improve the barcode readability at a larger size?
Thanks, Vlad

Answer 1

The size of a barcode is determined by the printer escape sequence,
which is sent to the printer to switch on the barcode.
Please go to transaction:
SE73 -> 'Printer Barcodes' -> Select your 'Device Type'
     -> You get a list of the barcodes, which the device  type is able
        to print. On the right side you see the names of two print
        controls: A prefix to switch on the bar code (SBP...) and a
        suffix to switch off the bar code (SBS...)
     -> Highlight the print control name with the cursor and press the
        'Displ. print control' button.
     -> You should now see the printer escape sequence that tells the
        printer to start the barcode.
This sequence selects amongst other things  the type and size of the
barcode.
To get another barcode size, it is required to change this sequence.
Please copy the device type to another name before changing:
SPAD -> Utilities -> For device types -> Copy device type.
If you use a Jetcaps barcode SIMM, the attached Note 45643 explains the
sequences. Otherwise your printer manual should be able to help you.
Overall width cannot be changed, have to change width of bars and
spaces.
