Vague JetDirect Problem

[wpl1 () jps net]

The subject reads "vague" because I'm not sure this is really a firewall
issue--but it could be.  We have installed a single JetDirect device in our
building.  The network sees the device and workstations may be configured to
recognize it.  Our building, in which a couple dozen workstations connect to
one of two daisy-chained hubs, connects to via fiber to the MDF in another
building where several dozen workstations are more efficiently connecting to
switches.  The JetDirect is connected to one of those two chained hubs in
our building.

The firewall is a Cisco PIX sitting off of one of the aforementioned
switches at the remote building.  There are three routers in the picture,
all located in the remote building.  One routes data from our building
across a WAN to yet another site; one routes across still another WAN; the
third is outside the firewall pointing to our ISP.

The JetDirect's configured gateway is the internal IP of the firewall.

Now, folks at the remote building (site of the MDF, et al.) can print to our
device.  We can print from our building to devices at the remote building.
But we can't print to our device.  (The printer never produces the job which
remains as a pending job according to the printer's status.)  The network
print server is a host connected to the switches mentioned above.  Is the
gateway configuration--which is the same for all successfully operating
JetDirects on the network--feeding the data by default to the PIX?  Is the
PIX possibly trashing the data?

The network is NT; workstations run 98.

Any assistance will be appreciated.  A simple reply of "Huh?" will be
understood, as well.  Apologies in advance for my not having sufficient
technical prowess to clearly describe this problem.
