When converting a postscript file to PDF using the following command line, the barcode elements are flipped 180 degrees counter clockwise, above the correct origin and overlaying text. The rest of the elements are correct. Adobe Distiller converts it correctly.
C:\tmp\gs_test>"C:\Program Files\gs\gs10.02.1\bin\gswin64c.exe" -dQUIET -o"DC2008y2_gs.pdf" -sDEVICE=pdfwrite -r812 -IFONTDIR="\asgard\production\Label System\Fonts;C:\Windows\fonts" -f "DC2008_001.ps" -c quit
Correct image from Adobe Distiller
If I add -c "<</Orientation 2>> setpagedevice" to the command line, it seems to rotate the labels from the bottom left origin, making it the new top right. This causes all of them to be shifted left.
