Can I hide the footer when printing a panel?

No, when printing a panel the footer can not be hidden. To print a panel the function printPanel() is used.

The function int printPanel(string modulName, string panelName, string spec [, bool ShowDialog]]) prints out a panel <panelName> in a module <modulName>.
The default value of spec = "" which means print with child panels like a screenshot. The value "panelOnly" means prints the panel without child panels (without screenshot of the child panels).
If the optional parameter "ShowDialog" is set to TRUE the printer dialog will open. To define the settings by using the attributes of the internal datapoint datapoints _Ui, set the value of the showDialog to FALSE.

When printing a table there is the possibility to change the format of the footer by a parameter. Hiding is also not possible. The function printTable() has a parameter "footer" which describes the format of footer. The following abbreviations may be used: \date \time \page \name \user \numpages The following parameters can be used for justification: \left{...} \right{...} \center{...} \fill{...} Line width and height are set by the paper format.
