       Business::TW::Invoice::U420->init_printer; my $u420 =
       Business::TW::U420->new
	   ({ heading => [ DateTime->now->ymd, '',
			   'order: #232', ''],
	      lines_total     => 35,

DESCRIPTION
       This module generates commands for the "Epson RP-U420 invoice" printer
       for printing the	Unified	Invoice	in Taiwan.

       You must	install	the driver and printer processor properly before you
       can use the module.

       You can define multiple lines of	headers	that will appear on each page
       of the printed invoices,	and when you do	println	the module does	all
       the necessary paging and	stamping for you.

METHODS
   new
   init_printer
   feed( $lines	)
       Feed $lines lines, default is 1.

   stamp
       Make the	printer	stamp on the invoice.  note that you generally don't
       want to call this method	directly, due to the stamp positioning.	 When
       you call	"cut", the module automatically	detects	the correct place to
       stamp for the next invoice.

   cut
       feed the	current	invoice	and cut, as well as stamping on	the next
       invoice.

   print
       Low level print function.

   println
       Print a line on the invoice.  Does all the paging logic here.

       Chia-liang Kao, "<clkao at clkao.org>"

   TODO
       o   Split the device control parts into "Device::Serial::U420" for
	   generic use and keep	the paging/stamping logic here

       o   Tests

       o   Add footer support
