quoth CPAN re Win32::Printer:

ABSTRACT ^
DISCONTINUED!!! Win32 GDI graphical printing ...

(and at 0.9.1, which reminds me of the old advice that one should never buy or use version 1.0 of anything)

OTOH, PM offers alternatives:

1. TGI's reply to node 678462 suggests using wx.
2. Q&A has How do I send a file to the printer on Win32?
3. and if you really want to get down to somewhat closer to where the metal meets the road, Win32::API

Hint: Super Search or Google could have helped here.

Update: In light of BrowserUk's well-made point (below), it seems to me that unless keithvb has some really good reason to output to html, he might also want to consider sending the data direct to a printer; to a text, .pdf or .rtf file; or skipping the html/browser phase (or tee'ing the data to it).
