Subject: [PATCH] Make window.print() configurable. The "Mozilla Print"
strategy is internally identified as 'webBrowserPrint', and it uses XPCOM for
printing the contents of an HTML document. However, in some cases we
override this with a 'window.print' strategy to workaround bugs. A problem
with this has been that an actual bare javascript window.print() does not
honor any of configured "gPrintSettings". However, it is informed by (and in
turn informs) a Mozilla preference called print.print_printer. Right now
window.print (if used from within the JSAN util.print library) only gets
called in when in the Default printer context/role. So we force
print.print_printer to equal the configured printer for the Default role.
Have I mentioned that I hate printing in Mozilla?
