Richard,
I see nothing wrong :(
Let's try this. I have attached a program which is exactly the code in
dt to send the file to CUPS. Nothing fancy and really straight forward.
To compile:
$ gcc -o dtprt dtprt.c `pkg-config --cflags --libs glib-2.0` -lcups
Then to send a file to CUPS:
$ dtprt workroom <pdf file here>
If you don't mind print the PDF and comment out one line at a time in
dtprt.c (see comment starting with ## with priority order) and check
again.
Alternatively you can try to comment out all lines and if the print is
ok add one at a time until it create a wrong print.
Thanks,
