Abstract
Abstract To process a plurality of types of information having different priority according to the priority, multiple logical channels are generated by combining a protocol in a transport layer of a network and a print queue in an application layer and priority is allocated to each logical channel. A host computer sends generated information to a predetermined logical channel by referring to a priority table. A printer discriminates the priority of received information by referring to a priority table and executes the processing of the information according to the priority. As a result, interrupt print data can be processed prior to normal print data or a control command can be processed prior to than print data.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
118 words
A printing system comprising: an information generator for generating and sending a plurality
of types of information which are different in priority; and a printer for receiving the information from the information
generator via a network and processing the information according to
the priority, wherein the network includes a plurality of logical
channels which are different in priority and belong to at least a
transport layer or an upper layer, the information generator sends
the information to the logical channels according to the priority
of the information, and the printer determines the priority of the
information based upon the priority of the logical channel through
which the information was received and processes the information
according to the priority.
Claim 2
Dependent Claim
41 words
A printing system according to Claim 1, wherein: said printer comprises a plurality of receive buffers which are
each allocated for a corresponding logical channel and have a size
which is set according to the priority of the corresponding logical
channel.
Claim 3
Dependent Claim
24 words
A printing system according to Claim 1 or 2, wherein: said plurality of types of information include normal print data
and interrupt print data.
Claim 4
Dependent Claim
23 words
A printing system according to Claim 1 or 2, wherein: said plurality of types of information include print data and
a control command.
Claim 5
Dependent Claim
36 words
A printing system according to Claim 1 or 2, wherein: said printer comprises a plurality of output trays; and said plurality of types of information include print data for
which a particular output tray is specified.
Claim 6
Dependent Claim
36 words
A printing system according to Claim 1 or 2, wherein: said plurality of types of information include print data in
which the printing language is designated and print data in which
the printing language is specified.
Claim 7
Dependent Claim
107 words
A printing method for generating and sending a plurality
of types of information different in priority and processing the
information received via a network according to the priority, wherein
the network includes a plurality of logical channels which belong
to at least a transport layer or an upper layer and a different priority
is allocated to each channel, the printing method comprising the steps
of: transmitting information via the logical channels according to
the priority; receiving the transmitted information and determining the
priority of the information based-upon the logical channel through
which the information was received; and processing the information is processed according to the
determined priority.
Claim 8
Dependent Claim
85 words
A printer for receiving a plurality of types of information
different in priority via a network and processing the information
according to the priority, comprising: a plurality of receive buffers which belongs to at least a
transport layer or an upper layer and which are respectively allocated
to a plurality of logical channels included in the network; discriminating means for discriminating the priority of
information received in the receive buffers; and processing means for executing requested processing according
to the discriminated priority of the information.
Claim 9
Dependent Claim
32 words
A printer according to Claim 8, wherein: a size of each of the receive buffers is set based upon the
priority of the logical channel to which each receive buffer is
allocated.
Claim 10
Dependent Claim
23 words
A printer according to Claim 8 or 9, wherein: the plurality of types of information include normal print data
and interrupt print data.
Claim 11
Dependent Claim
22 words
A printer according to Claim 8 or 9, wherein: the plurality of types of information include print data and
a control command.
Claim 12
Dependent Claim
33 words
A printer according to Claim 8 or 9, further comprising: a plurality of output trays, wherein the plurality of types of
information include print data for which a particular output tray
is specified.
Claim 13
Dependent Claim
36 words
A printer according to Claim 8 or 9, wherein: the plurality of types of information include print data in which
the printing language is specified and print data in which the printing
language is not specified.
Claim 14
Dependent Claim
90 words
A program recording medium for storing a predetermined
computer program for generating information to be sent to a printer,
the program comprising: a function for discriminating the priority of a plurality of
logical channels of a network which belong to at least a transport
layer or an upper layer; a function for generating a plurality of types of information
for transmission to a printer; a function for discriminating the priority of the information;
and a function for transmitting the information to a particular
logical channel according to the discriminated priority.
