Printing Barcodes to PDF from a WebServer Using TExtraDevices

I am using Delphi 6 with ReportBuilder Server 7.02, and TExtraDevices 2.6.
I am printing Code 39 Barcodes from a Report Server via a Web Tier. I have
set my barcode component to about 2 inches wide and about 0.15 inches high.
The BarWidth property is set to 0.011 and the WideBarRatio is set to 2.4.

I am printing Barcode that can be anywhere from 1 to 10 characters. I
display the report in a webpage I save it to a PDF using TExtraDevices, then
print a sample page. I can successfully scan 10 character Barcodes however
5 character Barcodes fail to scan using the same settings.

Does anybody have any suggestions?


Thanks In Advance

    Set the PixelsPerInch to 200 or 300 and set ScaleImages to false to render
    the best version of the barcodes for later scanning.

    I took a good close look at the barcodes that my report was generating.
    Using the same report I generated a PDF from my "Test Bed" application. I
    then generated a PDF via the web application. I printed out the same page
    in each PDF. I selected a couple corresponding barcodes in each page
    printed. I counted the dark bars in each barcode. I noticed that in the
    valid barcodes printed from the "TestBed" PDF there were 35 dark bars. While
    there where only 33 bars on the barcodes printed out from the Web generated
    PDF which doesn't scan. This looks like a possible bug to me.

    I would be most grateful for any fixes or work-arounds.
