Q. Can I use X-MED and X-GPD together? Are there instances when
you don’t
recommend using X-MED?
A. Yes to both questions. X-GPD and X-MED do have different workflows and
are intended for different purposes. X-MED is best suited for users who require
flexibility and convenience when printing, particularly when traveling. If the
network environment requires strict control over printing configurations, or the
are intended for different purposes. X-MED is best suited for users who require
flexibility and convenience when printing, particularly when traveling. If the
network environment requires strict control over printing configurations, or the
user has no need to switch to different printers, there’s less need for X-MED.
Q. How does X-MED employ specific protocols when sending print jobs?
A. X-MED uses a local port to enable print job transmission.
The user doesn’t
need to manage the selection of settings such as port 9100 vs. RAW.
Q. Which ports need to be open on routers / switches to allow for discovery
and bi-directional communications? Is there a specific port that SNMP
communications use?

communications use?
A. SNMP uses ports 161 and 162. In addition, the devices must support SNMP

X-MED. To prevent devices from being discovered by X-MED, change the
SNMP Community Name on those devices to use a name other than “Public”

Q. I clicked on the discovery icon in X-MED
, but the printer I’m looking for
didn’t show up in the “Discovered Printers” list. Why?
A. X-MED
’s discovery module uses SNMP requests to query for devices on
your network, within your local subnet. If your network is very large with
numerous print devices, you may need to run the discovery module more than
numerous print devices, you may need to run the discovery module more than
once to find the printer(s) you’re looking for. This is due to inherent limitations
in the SNMP protocol.

To force additional device discoveries, select the “Cancel” button from within X-

MED and then re-open the driver by choosing
“Properties” again from the
application’s Print dialog. (Another way to do this is to select any device from
the “Discovered Printers” list, click the “OK” button, and then click the “Change
Printer” button. You can then click the Discovery icon to launch the discovery
module and find additional printers.)

MED’s Advanced Network Search feature. Click the “Advanced
Search” button in the “Discovered Printers” window, and then specify the
printer’s IP address, or specify the device’s gateway and subnet mask.
You can also search for your printer directly by clicking on
the “IP Address or
DNS Name” button. Enter the printer’s IP address or DNS name into the
