Any third-party printer connector made for Business Centrallink
A printer must be able to print without "user interaction". This disqualifies many PDF printers as they typically require providing a file name before saving the file.
To verify you have a valid printer you must be able to print e.g. a Customer Top 10 report from the WebClient without having to preview the result first.
