Problems with Simulink to eps

Dear colleagues Probably from MATLAB 2012b, the exporting of Simulink to eps file is changed. The following command is OK bor either versions print -s -deps filename However, in the new versions, the file size generated is significantly inceased to 8M or so, with bitmap format of the whole page, rather than the vectorized exact size eps file in the previous versions. Is there any solution to this? Thanks
