If you're using *nix, it'll work but not on Winblows. The Printer docs say this:
"...on Linux/UNIX the data passed to the print method can be anything which should be printable, i.e. groff/troff, PostScript, plain text, TeX dvi, but on windows the only data which can be handled by the printing system is plain text, GDI commands or flies [sic] written in your printer's interface language."
