Problem with spacing and Pdfview

Hi, my drupal site is using pdfview to render nodes with no problems except when a line contains a single Enter with no more text (the spacing it renders is huge compared to paragraph spacing). Also i didn´t find in module or tcpf config file the settings for line spacing, paragraph spacing, etc(i´ve correctly changed font size, page size, etc... in tcpdf config).

thanks in advance!
