How is your printer connected ?  If it's using  The  Common  Unix  Print  System
(C.U.P.S.) as many do, try the lpr command (from `net-print/cups`).  The  server
on which C.U.P.S.\ is running is specified with the `-H <address>` argument, and
various options can be specified with `-o <key=value>`.

To take the example from the man page of lpr:

        Print a double-sided legal document to a printer called "foo":
        $ lpr -P foo -o media=legal -o sides=two-sided-long-edge filename

If your printer is remote, as mine is (on a server called `genserv`), you can do
the following:

        $ lpr -H genserv -o sides=two-sided-long-edge paper.pdf

This is not a suggestion that you abandon the issue  of  mismatched  Qt  library
versions, but rather a simple workaround to use while the  various  Qt  programs
get up-to-date with the latest versions of the libraries. Providing C.U.P.S.\ is
configured correctly with all the appropriate `ppd` files  for  your  particular
printer model, lpr should work out-of-the-box.
