Abstract

Since print speed of low-end page printer becomes higher recently, it becomes comparable to copier. Print cost per page of page printer is much cheaper than copier. It means that it is cheaper to print the number of copies as needed on printer than print a document, then make copies on copier. Many printer manufacturers such as HP, Epson, emphasize this cost advantage to their customers, and they put several functions into printers to make copies easier on printers.

Printer with keyword search capable reproduction function

Since print speed of low-end page printer
becomes higher recently, it becomes
comparable to copier. Print cost per page
of page printer is much cheaper than copier.
It means that it is cheaper to print the
number of copies as needed on printer than
print a document, then make copies on copier.
Many printer manufacturers such as HP, Epson,
emphasize this cost advantage to their
customers, and they put several functions
into printers to make copies easier on
printers.

HP introduces this capability as "Mopy" on
their printers. Mopy provides the function to
store a document as rasterized image into its
hard drive, and an operator can choose the
document stored in the hard drive using its
operator's panel, then reprint it. Since the
document stored is already rasterized,
printer can usually reprint it at its rated
speed.

On Mopy, an operator can specify only a job
name and a user name to identify the document
at print time. The operator has to find out
the document he/she wants to reprint with the
job name and the user name as the lead from
the operator's panel on the printer. It is
not convenient for an operator because the
job name and the user name he/she can specify
are very short to identify one if the number
of documents stored in a hard drive becomes
very large. This disclosure gives us a
solution to search the required document to
reprint from many documents stored in a hard
drive on a printer easier with keyword search
capability.

The followings are the theory of this
disclosure.
(1) Printer 1 has an auxiliary storage such
as a hard drive to store rasterized image.
Print data comes from host computer is
interpreted by the Interpreter Unit 2, and
rasterized image is generated. The
Interpreter Unit 2 is also determined whether
it stores rasterized image in the auxiliary
storage if it finds some specific order in
print data.
(2) If the Interpreter Unit 2 can not find
the order to store it, rasterized image is
passed to the Print Unit 4, then the Print
Unit 4 prints image onto paper as usual.
(3) If the Interpreter Unit 2 finds the order
to store it, it generates keywords used later
to find out the appropriate document at
reproduction time. Several ways can be

considered how to generate keywords. When
text date is embedded into print data as code
such as EBCEDIC or ASCII, we can pick up just
text data as word boundary and use them as
keywords for search. We can use this approach
for IBM IPDS printer datastream, ESC/P and so
on. When text data is sent to a printer just
as image such as pri...
