"Label print method code that the Labels are to be generated for EPL2 formatted Labels use EPL, for SPL formatted Labels use SPL, for ZPL formatted Labels use ZPL and for image formats use GIF, for Star Printer format formatted Labels use STARPL.

For shipments without return service the valid value is GIF, ZPL, EPL and SPL. For shipments with PRL return service, the valid values are EPL, ZPL, SPL, STARPL and GIF."

UPS does not return PDF labels. You have to convert the GIF that is returned into a PDF. You can do this easily using the 'convert' command of ImageMagick or using GhostScript.

Here is an example of 'convert':

convert  -bordercolor none -border 100x100  -page Letter ups.gif ups.pdf
