An install apparatus installs printer firmware to a printer through a network in the background of normal print jobs. The Printer () includes a storage means () to store the firmware consisting of a plurality of blocks, and a processing means () for receiving the blocks to store to storage means (). In case an interruption occurs during the firmware installation and at the time of resuming the installation, the processing means () informs install apparatus () of a guarantee range of the installed blocks being determined from the data stored in storage means (). The install apparatus then restarts transferring the firmware from the succeeding transfer block of the guarantee range.

Printer firmware installation method, printer and printer system

A line printer apparatus with which a printing control operation is carried out by using a printing mechanism and printing operation control unit in which the reversal of the motion of a printing unit is carried out in synchronization with the feeding of a paper to be printed. The apparatus includes a decision unit for deciding whether or not a shuttle carrying the printing unit should be stopped during the reversal of the motion in accordance with printing information supplied to a unit for controlling the driving of the shuttle and the condition of feeding of the paper; reversing motion stopping means for stopping the reversing motion of the printing unit and holding it in the stopped state by supplying reversing stopping information to the printing operation control means when the paper feeding time of the paper to be printed is greater than the time of the reversing motion of the printing unit; and releasing means for releasing the stopping of the reversing motion of the printing unit in relation to the timing of termination of paper feeding of the paper to be printed and restarting the printing from a printing starting position. Therefore, the printing operation is restarted immediately after the termination of a paper feeding operation even when the time of the paper feeding is longer than the time of reversing motion of the printing unit.
