ThinPrint prints with its own printer ports (ThinPrint Ports) which will be automatically created during installation. Thus, ThinPrint does not affect printing with conventional printer ports, such as Standard TCP/IP Ports.
This chapter describes configuration of the ThinPrint Engine with special attention to adding ThinPrint Ports and adapting them to specific requirements for print job transmission. The Port Manager offers the following options for ThinPrint Ports:
- Add a ThinPrint Port – local and remote
- Configure a ThinPrint Port – local and remote
- Delete a ThinPrint Port – local and remote
- Send port configuration to other Windows machines on which a ThinPrint Engine is installed
- Export and import port properties
- Encryption settings
Starting Port Manager
- Open the ThinPrint Configuration console.
- In case of remote configuration: In the ThinPrint node, click Add and specify the computer address.
Setting up ThinPrint Ports
To create new ports use the buttons New ThinPrint Port or New ThinPrint Connection Service Port in Port Managers menu bar. Choose the port settings: port type (protocol) and bandwidth and (optional) encryption.
Note!In principle, there is no limit to the length of printer port names. Some old applications, however, only support port names with a length of four or six characters; if longer port names are used, this could cause problems (printer is not visible in the application, etc.).
Pool not more than 20 to 25 ports because each printer of a pool must be assigned to all ports. Because of Windows restrictions the general rule is:
Length of port name x Number of ports < 200
- To configure ports, select from the Console Tree on the left: ThinPrint→ ThinPrint Engine→ Port Manager.
- Double clicking a port name will open the port configuration.
|Use encryption||Enables encryption; a valid and corresponding certificate must be available for both ThinPrint Engine and ThinPrint Client machine (not for LPD; see also Encryption of print data).|
|Bandwidth control||• Enable: Bandwidth control on
• Max. bandwidth available for printing with ThinPrint; minimum: 1 kbit/s, default: unlimited
|Print protocol||• TCP/IP (Sockets)
• Use Virtual Channel Gateway (Print data will be sent to the terminal server or virtual desktop and then sent via RDP, ICA or PCoIP with the Virtual Channel Gateway installed there)
• LPD (Unix print protocol LPR/LPD)
• Virtual Channel Protocol (ICA/RDP)
This function is not relevant here. It’s intended for direct printing from terminal servers or virtual desktops.
|Minimum print data volume||• Enabled: always highest compression
• Disabled: transfer rate optimized compression – depends on bandwidth settings
You can also select the TCP port (default: 4000) for TCP/IP (Sockets) and Use Virtual Channel Gateway print protocols (see the table above). With TCP/IP (Sockets), the TCP port numbers of the ThinPrint Clients (see Advanced tab) must be the same as those of the ThinPrint Ports. With Use Virtual Channel Gateway the TCP port numbers of the Virtual Channel Gateway(s) must be the same as those of the ThinPrint Ports.
For LPD printing, see LPR/LPD printing with Linux, Mac or Windows CE clients.
- Confirm changes with Apply or OK.
Under Advanced, you have the following options:
Client control: Bandwidth
If this option is enabled, each user can set her / his own bandwidth value (in the ThinPrint Client Manager).
Client bandwidth settings must be lower than server-side settings; otherwise, ThinPrint Port settings are applied.
Connection retries (TCP/IP and LPD only)
Enter the number of times ThinPrint Engine should attempt to establish a connection to the client.
Net Send Service
Net Send Service is used to notify users if ThinPrint experiences print errors. If this box is checked (= default), ThinPrint Engine will send error messages to the relevant account.
Note: This function can become irksome if several users are logged on using the same account.
You can select for each ThinPrint Port whether the address information is at the beginning or the end of the printer name. Examples:
|Default addressing||Reversed addressing|

Print statistics can be activated per ThinPrint Port.
- Select the relevant ThinPrint Port; click Properties→ Job statistics and then High (every second), Normal (every 10 seconds), Low (every 30 seconds), No update, or Statistics off (default) under Update speed.
Note! Use this function only part-time, as it may affect print performance. See also ThinPrint Tracking.
- Save your settings by clicking OK or Apply.
Distributing port configuration
The following strategies are available for creating the same configuration for ThinPrint Ports on multiple servers:
- Remote configuration of ThinPrint Ports (Starting Port Manager)
- Copying port properties with Copy&Paste (see below)
- Export to an .xml file and import to target servers (see below)
- Sending port configuration to target servers (see below)
- Open the ThinPrint Engine configuration console (Starting Port Manager).
- Mark a port in a server’s Port Manager (e. g. ts020) and select Copy from the context menu.
- Mark the Port Manager of a target server (e. g. ts012) and select Paste from the context menu.
The following export and import functions are available:
|Export Port Configuration||Exports the selected ThinPrint Port to an .xml file|
|Import/Export→ Export Port Configuration||Exports all ThinPrint Ports to an .xml file if no port is selected|
|Import/Export→ Import Port Configuration||Imports ThinPrint Ports from an .xml file|
The Send Port Configuration function sends ThinPrint Ports to other servers or server groups. There are various modes:
|Send Port Configuration (Overwrite)||Sends the selected ThinPrint Port; a port with the same name on the target system will be overwritten|
|Send Port Configuration (Add Only)||Sends the selected ThinPrint Port; a port with the same name on the target system will not be overwritten|
|Import/Export→ Send Port Configuration (Overwrite)||Send all ThinPrint Ports; ports with the same name on the target system will be overwritten|
|Import/Export→ Send Port Configuration (Add Only)||Send all ThinPrint Ports; ports with the same name on the target system will not be overwritten|
ThinPrint Ports that already exist on the target computer, but not on the sending computer remain unchanged.
- Selecting the send option will open the dialog.
- To improve clarity, first select Object Types, and disable Groups. Click OK to confirm.
- Select Advanced and then Find Now.
- Mark all target servers and click OK to confirm.
Caution! You are influencing the configuration of remote computers. Check once more that you really want to send the configured ThinPrint Ports to the selected servers. A confirmation prompt gives you the option to cancel the process.
Note! If you receive an error message when sending, create a connection to the target computer with the MMC, using the relevant ThinPrint Engine node for remote configuration (Starting Port Manager) and repeat the send process from the source computer while keeping the console open.
