FAQ: VMware Horizon and ThinPrint

Only a virtual printer is displayed – where are the others?

See the VMware article below: kb.vmware.com WINDOWS 7 DESKTOPS WITH THINPRINT DISPLAY ONLY THE DEFAULT PRINTER (1032872)

What can I do if the output and the original are different from each other?

Before you print, enable print preview in the (Output Gateway) printer properties in the View session. Check here if your print job already differs from the original.

Please refer to Incorrect characters or fonts in print output.

Why was my print job not delivered?

Before you print, enable print preview in the (Output Gateway) printer properties in the View session. This allows you to check if the print job reaches the Windows workstation. Try to print directly from the preview window. If this also fails, check the printer properties, or replace/update the printer driver on the workstation.

What can be done if the local default printer is not the default printer of the View session?

If the local default printer of a client computer is other than the default printer in a View session, and the user(s) have to reset it every time they log in, proceed as follows:

  • Delay the startup of AutoConnect on the View desktop by a few seconds, e.g. by changing the startup type of the TP AutoConnect service from AUTOMATIC to MANUAL and then start it using a script with:ping -n 10 >NUL
    net start tpautoconnsvc(10 = 10 second startup delay)

What can I do if my printer can’t be created?

Complete the following steps on the command line of the View session:

  • Change either – under Horizon View 5 – to the directory %programfiles%\VMware\VMware Tools
    or -– under Horizon 6 – to %programfiles%\common files\thinprint
  • Execute TPAutoConnect.exe -d (ends the current AutoConnect instance of the user)
  • Execute TPAutoConnect.exe -v (create a printer in verbose mode)
    An error message should appear in the output with a description of the problem.

If the manual creation of the printer with AutoConnect from the command line is successful, check that the following Timeout values are set in the Windows registry and, if not, set them:

  • on a virtual desktop in: hkey_local_machine\software\ThinPrint\TPAutoConnect
    TimeOutClientExecution [dword] “150000” (decimal)
    TimeOutVirtualChannelRead [dword] “130” (decimal)
    ListenToWTSTrys [dword] “450” (decimal)
    ListenToWTSTryDelay [dword] “2000” (decimal)
  • on a Windows.Client:
    PropertyRequestTimeout [dword] “120” (decimal)
    On 32-bit operating systems in: hkey_local_machine\software\ThinPrint\Client
    On 64-bit operating systems in: hkey_local_machine\software\Wow6432Node\ThinPrint\Client

Restart the TP AutoConnect Service in the View session, and, if necessary, also on the virtual machine and the View Client.

Why does it take longer to set up printers with Location-Based Printing?

The time to create a printer depends on the degree of functionality of the printer driver. It takes longer, for instance, on a printer with a universal printing driver than with a driver intended for a particular printer model.

How do I enter an IP range when configuring Location-Based Printing?

Use the following syntax to enter IP addresses in a particular range:

IP address – IP address

Use the following syntax, to enter in all the IP addresses in a particular subnet:

IP address / Subnet mask bits

The example provides that the IPv4 addresses from to are able to be used.

What settings can I make in Location-Based Printing configuration?

To set up Location-Based Printing, refer to the Setting up Location-Based Printing page at www.vmware.com.

How can I create a static printer on the client?

You can create a printer manually on the virtual machine using exactly the same settings as are used for a mapped printer (Printer port: TPVM:, driver: TP Output Gateway). All print jobs to this printer are now sent to the default printer of the View Client computer

However, if you would like to address a printer other than the Windows client default printer, then, in the View session, you should activate the print preview option in the Output Gateway user interface. In the preview, you can then select any locally installed printer.

Which printer properties are transferred when mapping local printers?

The following will be transferred from Windows or Mac computers to the printers in a View session:

  • paper size
  • paper source
  • color / black and white
  • page orientation
  • two-sided printing
  • a range of finishing options

How can local printer mapping be disabled?

To do this, you disable the TP AutoConnect Service on the virtual machine. Doing so, however, also disables Location-Based Printing.

If you want to have the option, of disabling only the local printer mapping, we recommend upgrading to our product ThinPrint Engine.

What is the difference between local print mapping and Location-Based Printing?

With local printer mapping, the printers are first installed on the View Client computer and then mapped in the View session. For Windows and Mac clients the printer properties are transferred to the virtual machine. In contrast, Location-Based Printing allows for the creation of printers that are independent of the standardized local printer mapping. These printers can have custom drivers, names and printer ports (of the type standard TCP/IP), which can be defined in the Location-Based Printing group policy.

How can I check the GPO for Location-Based Printing on a virtual machine?

  • Run the command gpresult /h gpreport.html on the command line. In the current directory, a report will be generated, which can be displayed in the browser. This report provides information on the active group policies and any previously made changes.
  • On the virtual desktop, the Location-Based Printing group policy creates the registry value PrinterCreateListEx2 in: hkey_local_machine\software\policies\ThinPrint\TPAutoConnect

Are client printers also mapped when Location-Based Printing is enabled?

Yes, even if Location-Based Printing is set up and enabled, the printers installed locally on the View Client computer are also mapped, in addition to the Location-Based Printing printers.

Where can I find the documentation or get support for VMware products?

The ThinPrint components included in VMware products are an integral part of each product.
