Note: This was originally posed to mozilla.support.seamonkey, but it was
suggested that I ask here as well.
I'm running SeaMonkey 1.1.4 on Linux (CentOS 4.5, equivalent to RHEL 4.5) and
have an HP LaserJet 4si printer accessed via TCP/IP. I'm using the CUPS printing
drivers (cups version 1.1.22, which is the most current for this OS).
When I print to this printer using Adobe Acrobat Reader or Gnome Edit (the only
other client applications I've tried), I am able to specify that the print job
should use the printer's Duplex mode.
However, when I print from SeaMonkey, I'm not given the option to select
I've downloaded and installed the most current PPD driver from here:
I selected the postscript driver, which was recommended:
However, this made no difference.
I've looked at the contents of the driver file, and it appears to have the
Duplex option enabled.
I've gone through the CUPS documentation, and I seem to have the printer
installed and configured correctly - and as I said above, it works
properly when accessed from Acrobat or Gnome Edit.
When I run lpoptions on the printer, I see all the available options, of
which Duplex is listed (the asterisk means that None is the default):
$ lpoptions -p hp4si -l
Smoothing/Resolution Enhancement: *True False
Duplex/Duplex (Print Both Sides): *None DuplexNoTumble DuplexTumble
ManualFeed/Manual Feed: True False
Is there anything I can do to get SeaMonkey to recognize that the printer
supports duplex mode?
