[Zope] Printing from Zope

Hello all: Not sure if this has been asked before, probably yes, but haven't been able to find anything yet. Does any of you has been able to print from a Zope application to a printer attached to the same machine where Zope is running, in my case it's a Red Hat Linux 6.1 box. I need to print from Zope with a specific printing format (like invoices, receipts, etc). This will be done on always the same Intranet and printing will be controlled from the Linux spooling system. If you can copy your comments to me by email besides the mail list, it'd be great. ,Any help is appreciated, thanks in advance. Felipe Barousse
