RPC error 1722 while printing

  • Some of my clients report that printing from WPRichText is not possible, program reports "system error RPC 1722". At the same time, printing in any other way or any other programs is possible without any problems.

    Sometimes it can be fixed by changing some advanced Windows settings, sometimes not.

    I wonder, what kind of non-standard printing procedures are used in WPTools that can cause this error, is there any walk-around?
