How to get extra content blocks to print with the Printing module?

[kermit]

doesn't the print module only pull {content}?  

have you looked at this parameter.

(optional) includetemplate="false" - If set to 'true' this options makes the print/pdf process the whole template, not just the main content. This probably requires some work on print-specific styles with the mediatype 'print' enabled.

i've never used the print module.. i just make sure the print media stylesheets make sweet output.

is there a solution for this? becaus in my main template i am embedding my content this way:
{content assign="Column1"}
{content block='Content_right' assign="Column2"}
{$Column1}
{$Column2}

and therefore i tried to replace the {content} tag in print template with {$Column1} and {$Column2} but this wont work

but when i use {get_template_vars} there is just the {content} tag. what should i do now?
