6. When clicking the Printer Sharing option, a dialog will be
displayed with all the printers which are installed through nuport-admin tool.
7. Select the check box to enable the Printer Sharing feature. & De-select to disable it. If the Printer
is already connected to the Client PC and then Printer Sharing is selected a message box is displayed to
disconnect the printer before enabling Printer Sharing when we click on the "Save" option.
Enabling Printer Sharing will turn OFF the Auto Connect feature for the device which is mentioned in the
"Note" section in the dialog.
Giving the print job:
----------------------
1. Go to the printer tray.(Control Panel\\Printers and faxes.) and give a print on the offline printer.
2. This will load the printer drivers and sends the print job to the printer and unloads the printer
when the print jog is done.
3. Suppose more than one using the same printer, your job will be in the queue till the printer is free.
Note:
------
- Suppose user dont want any Printer Sharing feature for a particular printer, then first uncheck that printer in Printer Sharing dialog.
Then issue a connect request in Devicesmapping functionality manually, It will load the printer and print job can be fired on it.
- When the print job is done, Click disconnect.
- If you have not unchecked in the Printer Sharing dialog, It will displays a message "This Printer: printer name is already
Installed & It is in Printer Sharing Mode.".
- Lexmark Inkjet Z645 printer: It displays a warning message “Communication Not Available” in printer sharing mode.
When you say “Ok” and respond to that message, the print job gets scheduled successfully. This is not a problem.
It gets appears because of the reason that print job is given on an offline printer.
Printer Related Info On Device Details View :
-------------------------------------------------------
- If the device is of printer class, then on the device details view, it will appear as Printing Support - Available.
- If the printer drivers are not installed, then it will appear in the device details view as below.
Printing Support - Available.
Mode: Not Configured.
From this information user can find out that the drivers for this printer are not installed.
- If the printer drivers are installed, then the printer name will appear as below.
Printing Support - Available.
Printer Name: "HP DeskJet XXX"
- If the printer drivers are installed, along with the printer name, Printer Sharnig mode related details are also shown as below.
Printing Support - Available.
Printer Name: "HP DeskJet XXX"
Mode: Printer Sharing / Manual
From this information user can find out whether the device is configured in Printer Sharing mode or not.
Remove Option in "printer sharing" dialog:
------------------------------------------------------
When the user invokes the printer sharing dialog, (by clicking on the printer button on the tool bar),
it scans through the newly installed printers and saves this information.
Then it displays all the printer entries which are saved.
Here we have an option of "Remove", which helps in removing the printer entries from the saved information
related to Printer sharing feature. This "Remove" option helps in removing the obsolete printer entries only.
Here obsolete printer means, the printers which are uninstalled through printer applet.
If one tries to remove the printer, which is not an obsolete one, the utility will prompt the user
that "Printer XXX: Is not a obsolete printer!!" and it will not allow the user to remove the entry.
Auto Launch of Application:
--------------------------------
This feature allows users to configure device's properties to launch a specified application when it is connected.
It can be done by first selecting the "Settings" after right clicking on the device in the Admin Utility and
specifying the path of the application which is to be launched and then clicking "Save".
To turn off "Auto Launch of Application" user needs to uncheck the Check box and then click on Save.
To turn it on the Check box has to be Checked by clicking on it.
Device Request:
-------------------
- This feature allows a user to request another user for freeing a device which he has connected to.
- This will send a request to the other user and if he wishes to relinquish the device he shall accept the
request after which the device will be freed.
- If the user doesn't want to free the device he simply ignores and so the device's state will not be changed from "busy".
Auto Connect:
------------------
It is a feature which allows the newly added devices to be connected automatically.
New device is a device which is added newly and not already in the list of devices displayed in the Admin Utility.
There is a global "Auto Connect" enable / disable option available under "File->Settings" option.
Disabling this option will turn off auto connect feature for all the devices.
Enabling this options will take the device specific auto connect value in to consideration.
Auto connect can be configured per device basis through device settings option (Available in the context menu when we right click a device).
This option will be disabled, if the global auto connect option is turned off.
Auto connect enable / disable status can be seen in one of the column of admin utility "Device Mapping" view.
Note:
1. Auto Connect feature works only for new devices as said i.e if a device is made free by some one, it will not be connected since its an old device.
2. If a printer device is in "Printer Sharing" mode, then it will not be auto connected.
3. If we configure a printer in "Printer Sharing" mode, "Auto Connect" for this device will be turned off.
4. If we try to enable "Auto Connect" feature for a printer which is in "Printer Sharing" mode, through device settings, it will prompt a message box
saying that it can not be configured in to "Auto Connect" mode as it's "Printer Sharing" mode is already enabled.
Reconnecting to the devices when there is an Abrupt Disconnect:
-----------------------------------------------------------------------------
- Admin Utility connects to the devices which were lost either due to a link loss or unplug.
When the devices come back to the network they are connected automatically based on the following.
a) In case of link loss, only the devices which have their "AutoReconnect" value SET are connected to again.
b) In case of Unplug, only the devices which have their "Autoconnect" value SET are connected to again.
Note:
- You will see a reconnect happen in a link loss scenario, when the link loss is for greater than Unload wait time, only after which the utility unloads
the devices.
- Autoconnect feature addresses unplug of devices for any length of time and then connected back. A quick unplug and plug of a device also it addresses.
- When the devices are being reconnected in the above scenarios, the status in the GUI is shown as "Reconnecting".
After the link comes back, Admin Utility tries to reconnect to the devices. If it succeeds before AutoReconnectExpiry time,
it shows in the GUI as "Connected" or else shows in the GUI as "Busy".

Registry Configurable parameters: Date: 10:23 AM 11/2/2006
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Following are the configurable parameters of the usbipbus driver, which can be added in the registry at location
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VUSB\Parameters.
S.No KeyName Key Type DefaultValue(decimal) Range
1. MaxConfigDescCount REG_DWORD 4 Min 4 - Max 10
2. MaxInterfaceCount REG_DWORD 10 Min 10 - Max 16
3. MaxPipeCount REG_DWORD 16 Min 16 - Max 64
4. MaxIrpContextCount REG_DWORD 16 Min 16 - Max 512
5. AutoconnectDelay REG_DWORD 3000 (milli seconds) Min 3000 - Max 10000
(Note: "AutoconnectDelay" is the frequency of polling, for checking the printer availability when the printer is configured in Auto Reconnect mode.)
6. EnableRegisterIntf REG_DWORD 1 0 / 1
7. AppAliveWaitTime REG_DWORD 30,000(milli seconds) > 10,000(milli seconds)
Configuring MCS7830:
---------------------------
Make the following settings in the registry for making MCS7830 to function properly.
- Add a key "MaxIrpContextCount" of type REG_DWORD at location
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VUSB\Parameters
- set its value to 80(decimal)
- Restart the PC for the new settings to take effect.
- Now virtualize the MCS780 device. It should work fine.
Configuring MCS7720
---------------------------
- Getting rid of retries / connection timeout / error in packet format :
We get this retries / connection timeout / error in packet format etc. because of the overrun errors.
To over come this, from the device manager, enable the HW flow control & increase the Receive Buffer Size
to 2K for the MCS7720 serial ports. Now it will work fine up to 921600 baud with out any problem.
This is required because the device is on the network and also HyperTerminal issues a receive call for just
80bytes only which is very small, which causes the over runs to happen.
- Working with multiple MCS7720 & 7740 devices :
When 2 MCS7720/7740 devices are connected, there is a possibility of more incoming IRP's when multiple
ports are opened. So make the following settings in the registry for the device to function properly.
- Add a key "MaxIrpContextCount" of type REG_DWORD at location
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VUSB\Parameters
- set its value to 80(decimal)
- Restart the PC for the new settings to take effect.
- Now more than 2 MCS7720/7740 devices should work fine.
