[Barcode4j-users] Poor quality barcodes in pdf from Barcode4J + Jasper

[Robert M. <rm...@em...>]

I have been trying to get reasonable barcodes to be generated from  
barcode4j and jasper reports on a Citizen CLP-621 203dpi label  
printer.  Ultimately, we have determined that if one creates a pdf w/  
a barcode (as small as possible) and prints it using Adobe Reader 7.0  
(print as image) a scannable barcode is produced.  However, if that  
same pdf is printed with Adobe Reader 8 or 9, the barcode appears  
scaled which results in very thick bars that are no longer scannable.   
In fact, it almost looks like Adobe Reader converted the svg barcode  
to 72dpi and then sent to the printer.

Does anyone have any experience with this?  We have a web-based  
application where our customers will need to print these barcodes, and  
having them downgrade to Adobe Reader 7.0 is not a desirable option.  :)

FYI -- our barcodes must be very small to fit on the label -- these  
ones produced with Code128A and a barWidth that amounts to 1 pixel @  
203dpi comes in (without quiet zone) at about 14mm (I believe when I  
dumped the SVG it indicated it was 18mm).  The barcode can not be  
larger than 20mm and fit on the label.
