Paul,
You may want to check CUPS error log at /var/log/cups/ on your print
server for any possible clues regarding PDF non-printing. Note the job
number for your PDF print job (lpq or lpstat on print server) and then
look for the entries with the same Job ID in CUPS error log.
I often see print errors for PDF files with partially embedded fonts.
Setting Adobe Reader to send all fonts at start cures this, but I'm not
sure if that option is available via lpr or lp.
You can try `lp` instead of `lpr`.
You can also try a different driver/PPD for your HP 5MP. Go to
http://your_print_server:631, Administration, Manage printers, select
printer, Admin., Modify. You might have a choice in between Gutenprint
and Foomatic/Postscript "models".
