One of our clients asked for a way to print clear quotes from their SugarCRM secure install.

The annoying matter being caused by the otherwise handy sub panels laying beneath the detail view of the quotes, or whatever some module would display in the main.

Solution: comment out all arrays in the following two files:

/modules/Quotes/metadata/subpaneldefs.php

/custom/modules/Quotes/Ext/Layoutdefs/layoutdefs.ext.php

The above paths are working for the Quotes custom module.
Below goes the path for any custom SugarCRM modules:

/modules//metadata/subpaneldefs.php

/custom/modules//Ext/Layoutdefs/layoutdefs.ext.php

Make sure to replace with the actual name of the module in cause.

Oh yes, forgot to mention you should toggle the left colum before hitting the [Print] button top right.
