I have this problem with at least 3 clients when they print to a Network printer, i.e. Printer connected directly to Network via IP address. This occurs with HP or kyocera. When an Invoice is Printed to this printer it first throws out a BLANK page with a small 'd' in the top left corner. The invoice is then printed correctly on the following page. However if one REPRINTS the Invoice this does not occur. The settings for LOGO etc are as they always were, OFF or not ticked.
I have tried re-installing printer drivers but with no change. All other programs, i.e. Excel, Word print normally without throwing out this extra page.
