Proprietary ones. Epson, HP, etc. all use their own mechanisms for that sort of thing, so you'd have to study their drivers to work out how their status utility queries the printer.

Hard work. :rolleyes:

Windows XP introduced the Bidi API (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdi/prntspol_2c1g.asp) for this purpose. However, I suspect that driver support for this relatively new API is rare or non-existant.

Some printers support SNMP as outlined in RFC1759 (http://www.faqs.org/rfcs/rfc1759.html) and used by tools such as npadmin (http://npadmin.sourceforge.net/) and ceps (http://ceps.sourceforge.net/).

Also, take a look at escputil (http://gd.tuwien.ac.at/linuxcommand.org/man_pages/escputil1.html) and libinklevel (http://libinklevel.sourceforge.net/).
