Abstract

<P>PROBLEM TO BE SOLVED: To facilitate the installation of a printer driver. <P>SOLUTION: A printer system can be used only by the installation of a printer driver in a printer even without the installation of the printer driver in a host. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a printer driver in a printer system.

  Conventionally, there is a printer driver in a printer system that transmits (outputs) recording data and commands to a printer using a printer driver and records the data on a recording medium (Patent Document 1). In installing the printer driver, the printer system cannot be used unless the printer driver is installed on the host, and the printer driver is usually installed on the host.

  In this case, the printer driver is stored in a storage medium such as a hard disk of the host.

  In this method, when one printer is connected to one host, or when a plurality of printers are connected to one host, the printer is used only once per host. Since it is only necessary to install a driver, there is no problem in such usage.

  However, the prior art has the following drawbacks. When one printer is connected to a plurality of hosts for use, printer drivers must be installed on all the plurality of hosts, resulting in a heavy workload.

  Also, the printer driver could not be installed if the host's hard disk capacity was insufficient.

  Furthermore, there is a case where it is desired to execute the printer driver temporarily different from the printer driver currently installed on the host but not to install it on the host.

Even if you just want to run a version that is temporarily different from the printer driver currently installed on the host, you must install and use the original version of the printer driver again after installing and using it on the host. The work was quite troublesome.
JP-A-8-328776

  The present invention eliminates the above-mentioned drawbacks of the prior art and solves the following problems.

  Instead of installing the printer driver on the host, install the printer driver on the printer.

  In this case, the printer driver is stored in a rewritable storage element such as a printer's Flash ROM.

  In this method, when one printer is connected to multiple hosts, it is not necessary to install a printer driver on all of the multiple hosts, and the printer driver is installed only once on one printer. Therefore, the work load is extremely small in such a usage pattern, which is very effective.

  In addition, if the hard disk capacity of the host is insufficient, the printer driver could not be installed. However, by installing the printer driver in the printer, the host hard disk is not used, so that the installation cannot be performed.

  Even if you want to run a version that is temporarily different from the printer driver currently installed on the host, it is not necessary to reinstall the original version of the printer driver after installing it on the host once and using it. Can be less troublesome.

  Even if you do not install the printer driver on the host, if you install the printer driver on the printer, the printer driver is automatically installed on the host when you actually use the printer system, and it is automatically uninstalled when you exit. The

  As described above, when installing a printer driver in a printer system that uses a printer driver to send recording data to a printer and record it on a recording medium, the printer driver is installed in the printer without installing the printer driver in the host. If installed, the object is to provide a printer driver installation method that can use the printer system.

  In order to achieve the above object, a printer driver installation method according to the present invention is a printer driver installation method in a printer system that outputs recording data to a printer and records it on a recording medium. If you choose to install the printer driver or install the printer driver on the printer, and if you choose to install the printer driver on the host, install the printer driver on the host, and install the printer driver on the printer. If you choose to install, installing the printer driver on the printer, determining whether the printer driver is installed on the printer, If the printer driver is installed in the printer when using the printer driver, the printer driver is automatically sent to the host for installation, and the printer driver installed in the printer is sent to the host for installation. If a different version of the printer driver is installed on the host in advance, do not perform an overwrite installation.If you install the printer driver installed on the printer by sending it to the host, install it on the host in advance. If a different version of the printer driver is installed, do not perform an overwrite installation and then install a different version of the printer driver installed on the host in advance. If the printer driver is installed by sending it from the printer to the host and whether to uninstall the printer driver sent from the printer to the host when the printer driver is terminated If you choose to uninstall the printer driver that was installed by sending from the printer to the host, uninstalling the printer driver that was sent by sending from the printer to the host, and host from the printer If you choose to uninstall the printer driver that was sent to and installed, if a different version of the printer driver was previously installed on the host, it was previously installed on the host. Steps to enable use of a different version of the printer driver and to uninstall the printer driver installed on the printer if you choose not to uninstall the printer driver that was sent from the printer to the host and installed If it is selected not to uninstall the printer driver that has been transmitted from the printer to the host and installed, a different version of the printer driver that has been installed in the host in advance is uninstalled.

  As described above, the present invention has the following effects.

  Instead of installing a printer driver on the host, install the printer driver on the printer, and if one printer is connected to multiple hosts and used, install the printer driver on all of the multiple hosts. Since the printer driver need only be installed once in one printer, the work load is extremely reduced in such a usage pattern, which is very effective.

  In addition, if the hard disk capacity of the host is insufficient, the printer driver could not be installed. However, by installing the printer driver in the printer, the host hard disk is not used, so that the installation cannot be performed.

  Also, if you want to run a version that is temporarily different from the printer driver currently installed on the host, there is no need to install the original version of the printer driver again after installing it on the host once and using it. , Can reduce the troublesome work.
