Abstract: A method of producing a high-strength high-toughness martensitic stainless steel seamless pipe which includes heating a martensitic stainless steel raw material to an austenitic range and subjecting the raw material to piercing and elongating to form an original pipe. The original pipe is cooled to form a structure substantially composed of martensite in the original pipe. The original pipe is reheated to a temperature in the dual-phase range between the Ac1 transformation point and the Ac3 transformation point, and is subjected to finishing rolling at an initial rolling temperature T (° C.) between the Ac1 transformation point and the Ac3 transformation point. The original pipe is then cooled to form a processed pipe. The processed pipe is tempered at a temperature below the Ac1 transformation point. The reduction in area R in the finishing rolling step may be in the range of 10% to 90%, and the initial rolling temperature T and the reduction in area R may satisfy the relationship 800≦T−0.

Consequently, it is possible to provide the high-strength, high-toughness seamless steel pipe used for a line pipe in which grade X80 strength and toughness are stably ensured, and the target strength can be easily attained regardless of the size.

Abstract: A print application (703) issues print job grouping start and end instructions to a print system (client) (707). The print system (client) (707) reads out the job information spooled at the time of reception of a grouping start instruction from a spooler (705) and stores the information. The print system (client) (707) reads out job information spooled at the time of reception of a grouping end instruction from the spooler (705). The print system (client) (707) then extracts jobs that do not coincide with the stored job information as print jobs to be grouped from the spooler (705) and outputs them.

Abstract: When a group print job is to be processed, a print application issues a grouping start instruction to a print system client first. The respective print jobs are then transmitted to a spooler. The print system client extracts the print jobs and sends them to a printer in accordance with scheduling by a print system server. In this case, if a transmission retry, transmission error, error after transmission, or the like occurs in a member print job belonging to the group job, the corresponding status is set as the status of the group job. The subsequent processing is performed as if the error had occurred in the overall group job.

Abstract: An apparatus capable of normally printing when the transmission of print data is interrupted by a user is provided. When the transmission of print data is interrupted by the user, a computer transmits an interruption command to a printer, and the printer totally clear the received data if it has determined that the interruption command is included in the received data. Otherwise, the size information of the print data is transmitted in advance, and determination of whether or not the print data can totally be received is performed by comparing the size of the received print data and the size information when the transmission of the print data ends. In the above manner, no data remains inevitably in a buffer in the printer when the process of one job ends, which enables the next printing.

Abstract: A client transmits only job information of print data to a server, the server manages a print order in accordance with the job information, and if printable, the client transmits the print data directly to a printer. After the print is completed, the printer notifies the server of a print completion, and upon reception of this print completion notice, the server instructs the client to delete the print data. In a print system on a network configured as above, the network traffic is not increased, a large memory capacity is not necessary for the server so that the server load is reduced, the job management of the server can be performed by the client, the completion of a print operation can be monitored, and a print operation is possible even if the server is in an error state.
