How do I resolve problems with Mamut Virtual Printer and printing to PDF?

article ID: 2023654 

Printing from Mamut to a PDF sometimes stops working because of problems with the printer driver Mamut uses to generate the PDF-files. This may be caused by problems with the installation, conflicting drivers or problems with the printer service in Windows.

Here are some tips for getting the driver installed properly and working:

1. Verify that the correct version of Mamut Virtual Printer is installed

Different versions of Mamut use different versions of the driver and have different names. Check your version of Mamut and the version of the driver installed.
◾In Mamut version 11.0 to 11.1 Mamut Virtual Printer 2 is installed.
◾In Mamut version 11.2 Mamut Virtual Printer 3 is installed.
◾In Mamut version 12.1 to 12.3 Mamut Virtual Printer 4 is installed.
◾In Mamut version 12.5 to 17.2 Mamut Virtual Printer 5 is installed.
◾In Mamut version 18 Mamut Virtual Printer 6 is installed.

Older versions of the driver from previous versions of Mamut may sometimes remain and cause problems. Delete these drivers and reboot if they are present.

2. The driver is installed but is not working

Sometimes the driver is installed but there have been problems with permission or the printer service in Windows. This usually solves the problem:


1. Uninstall/Delete all of the printer drivers with the name Mamut Virtual Printer or Amyuni in Windows. Set the viewing window to display the details of all the printers that use Amyuni drivers.
2. Reboot the machine and log in as administrator.
3. Repair Mamut as described in point 3 below.
4. Start Mamut by running as administrator and print a report to PDF.

3. Mamut Virtual Printer is not installed

There can be multiple causes for the driver not being installed. Reinstall as follows:
1. Go to the folder containing Mamut's installation files and run Setup.exe.
2. Choose to repair when you get the option of uninstalling or repairing.
3. Complete the install wizard to let Mamut repair itself.

4. Mamut Virtual Printer is installed but the print comes out on a regular printer

This is due to problems with the print service on Windows. The solution is to uninstall all of the printers as follows

 

1. Delete/Uninstall all the printer drivers in Windows

2. Restart the computer

3. Repair Mamut as point 3 above describes

4. Download and install the latest printer drivers for your printer from the manufacture’s website.

 

5. When printing the driver returns error -20, -30, -40 or -41

This may be caused by the driver using the wrong port or conflicts between the driver version and Mamut version.

Check the port in the following way:
1. Open the Control Panel - Devices and Printers.

2. Right click on Mamut Virtual Printer X and select Printer Properties.

3. Select Ports.

6. Select Local Port and click New Port.

7. Enter the name NUL and click OK.

8. Click Close.

9. Select the port NUL and click OK.

10. Test printing to PDF from Mamut.

 

If the port is correct but printing to PDF still fails there is something wrong with the driver installation.

5. Select the tab Drivers.

6. In Windows 7/8/2008/2012, click the button Change Driver Settings.
