Attached are two examples of pdf files that are auto-rotated 90 degrees no matter the Custom pagesize or orientation requested on the command line.
Also attached is the PPD file that comes with Stretch although it bears mentioning that neither the Wheezy nor the Zebra supplied PPD files fare any better. These files print either in landscape or portrait orientation as requested by custom pagesize in Wheezy. Thanks. Mark
