[Typo3] print tt_products basket & finalize pages

[Harry Jung]

Good evening,

i would like to print the last page of a tt_products fulfillment.

After the mail is sent to the customer, he/she should print out the page 
with all the necessary information:

1. Selected Products
2. Name, Email, address etc.
3. Shipping & Payment Information
4. Total-Price etc.


Problem:
-----------
The data besides of the products is such dynamic, so that in the print 
output only the products appear, but not the rest of the information.

In the TS-Setup i put the standard config for printing:

[..]
page.21 = TEXT
page.21.value = printable version
page.21.postUserFunc = tx_make_printlink
page.21.postUserFunc.target = _blank
page.21.postUserFunc.make_user_int = 0
[..]

But it seems (and that is logical) that the engine refers only to the 
'basket-PID', where this data isn´t available.

So my question is: How can i get this working ?

Can i specify an extra PID for the finalize page in the Setup/Constants 
like 'plugin.tt_products.PIDfinalize = 1234' <- doesn´t work.

Of course i can use "javascript:window.print()", but this is not what i 
want, regarding layout / rendering issues.

Any ideas are highly apreciated ;-)

Best regards,
