Coffalyser.Net requires the presence of a properly installed and available printer. Make sure that a printer is installed and that the default printer is working. If no printer is available, it is possible to install a software-based PDF printer to work around this issue.

Background

Coffalyser.Net uses a third-party library to help generate PDF reports. This library requires the presence of a printer in order to retrieve certain settings – even if you have no intention to print. If no printer is available, or if the default printer is not installed properly or not accessible, the following error message will be displayed:

No printers are installed.

This error message will be accompanied by the following raw exception message:
