Sometimes the format of the folio, check and reports comes out incorrectly when printed through Opera. The reason is the printer settings.
In cases like this, access the printer settings using the CTRL+P shortcut while viewing a report or any document.
Select either FIT or SHRINK TO OVERSIZED PAGES under the Size Options and PRINT. You only have to perform this once and the system will automatically print in the last selected format on the following printing processes.
