- the developers and service technicians can also perform operating actions using the graphical user interface 10, for example using the graphical function keys on the toolbar 12, and call up user interfaces that are also available to other operators.
- the setting values of the associated control variable can be changed by entering other values in the “Value” column in section 16 of the graphical user interface 10.
- the control variables contained in the “Key” column relate in particular to settings for generating and arranging and for evaluating so-called position marks. Above all, the position marks serve to correctly position, ie position, a print image that is generated on a carrier material by a second printer for a first print image that has already been generated on the carrier material by a first printing unit.
- FIG. 2 shows the graphical user interface 10 according to FIG. 1.
- the same elements have the same reference symbols.
- menu 14 “PNV marks” has been activated, as a result of which, in section 16, an operator interface for setting the position of the PNV marker, which serves as a position marker, is set or adjusted by an operator.
- the operator interface contains graphic slide controls 20, 22 for setting a vertical and a horizontal offset of the PNV mark, wherein the vertical offset can also be entered in the input and output field 30 and the horizontal offset also in the input and output field 32.

- a value that can be set using the slider 24 can also be set in the input field 34, a value that can be set using the slider 26 in the input and output field 36, and a value that can be set using the slider 28 adjustable value can also be entered in input and output field 38.
- Section 16 with the user interface for the PNV mark also contains a graphical representation 40, in which the position of the PNV mark is shown on the carrier material in accordance with the settings of the sliders 20 to 28.
- the length dimensions processed by the control units as internal control variables are specified in the millipoint unit.
- One millipoint corresponds to 0.0547 ⁇ m or 1/72000 inch.
- the position of the position mark, the dimensions of the position mark, the paper format and other length dimensions are stored in the printer as values converted into millipoint. These values specified in Millipoint thus serve as tax data.
- a country code is preset in a memory area of the operating unit of the printer, the country code being encrypted, for example, as a hexadecimal value.
- the hexadecimal value of the country code is stored in a memory area of a further control unit of the printer.
- the country code for Germany and the unit of measure for customs are assigned to a value 17hex stored there.
- the country code DE and the unit of measurement mm are assigned to the value 18hex.
- the value lFhex is assigned to the country code US and the unit of measurement inch.
- the length values saved in Millipoint are converted for display using the graphical user interface based on the preset country code or the unit of measure associated with the country code for displaying the length dimensions.
- the length measurements stored in Millipoint are converted and displayed for display as operating information with the preset country code. If a length specification, for example in inches, is output, the corresponding amount of the length measure is converted from millipoint to inch and depends on the preset language in a field behind the numerical value, eg for DE “inches” and for US “inches”.
- a large number of additional operating information, which are output with the aid of the graphical user interface, are formed with the aid of links of several control variables and / or several control and operating states.
- at least one piece of control information from each control unit of the printer is required, which signals the readiness for operation of the respective control unit.
- the signals of the control units are preferably linked to one another by means of a ÜND link, the link result being used for the readiness display for the printer and output as operating information using the graphical user interface.
- the individual control data are stored on a communication level, e.g. with the help of SNMP commands.
- the control data transmitted using the SNMP commands are preferably output using the user interfaces provided for this purpose on the operating unit of the printer or copier. Preferably only service and maintenance technicians have access to the user interfaces, through which the control data can be input and output, in order to avoid confusion of the usual operating personnel and incorrect operation.
- Control data are also referred to as machine parameters.
- FIG. 3 shows the graphical user interface 10 according to FIGS. 1 and 2.
- menu item 41 "offset" has been selected, section 16 of graphical user interface 10 showing a user interface for setting the offset of the printed images that are generated on the front and on the back of the carrier material.
- the print image of page 1 (front side) is generated with the help of a first printer and the print image of page 2 (back side) with a second printer.
- the carrier material is an endless carrier material which, after being output from the first printer, is fed to the second printer.
- the positioning of the print images takes place depending on the position mark generated with the aid of the first printer.
- a horizontal offset of the printed image on page 1 is determined with reference to the position mark.
- the horizontal position of the printed image on page 2 is determined in relation to the position mark.
- the vertical offset of the printed image of page 1 and with the help of the slider 48 the vertical offset of the printed image of page 2 with respect to the position mark.
- the print images of page 1 and page 2 must be shifted by shifting the setting controls 42 and 44, respectively. It is relatively complex to move the slider 42 in the same way as the slider 44.
- the slider 42 can be coupled to the slider 44 in such a way that when this graphical function key 50 is activated when the slider 52 changes, set value, the setting value of the slide controller 44 is changed by the same amount. It is thereby achieved that the value of the slider 44 'is changed depending on the value of the slider 42. Even when the setting value of the slider 44 changes, the setting value of the slider 42 is automatically changed by the same amount when the graphical function key 50 is activated.
- the setting values of the sliders 42 and 44 can still be set independently of one another.
- the sliders 46 and 48 can be coupled in the same way as the sliders 42 and 44. The operating actions required by an operator for setting up the two printers for preparing print jobs are thereby considerably reduced and errors are avoided.
- FIG. 4 shows a block diagram for the access of operating units 70, 84, 86 to data of the printing system with the aid of network protocols and a remote method involvement communication.
- Fig. 4 there are only components, i.e. Assemblies and functional units of the printer 52 are shown which are required for controlling operating units 70, 84, 86 according to the invention and for external access of the operating units 70, 84, 86 to the internal data of the printer 52.
- the control units 70, 84, 86 are also referred to below as control panels 70, 84, 86.
- the printer 52 contains a so-called web server 54 which has access to a memory area 56 in which data for displaying a so-called web page is stored, this web page serving as a graphical user interface for the printer 52 and on a display unit of an operating unit 70, 84, 86 is output using a display program.
- the display program is executed by a data processing system of the control unit, wherein the data is for displaying the web page using a 'Hyper Text Markup Language and / or generated in the Java programming language.
- the printer 52 also contains a control panel server 58, by means of which RMI communication with an operating unit 70, 84, 86 takes place.
- the control panel server 58 has access to memory areas 60 and 62, printer data and settings for generating a graphical user interface, so-called User data, are stored.
- the memory area 60 also contains data for outputting operating information and printer parameters and the memory area 62 contains data for authenticating the respective user and / or the operating unit.
- the Be 'serving box server 58 is connected to an internal network, such as a Local Area Network (LAN), which is operated by means of a Simple Network Management Protocol. With the aid of such a simple network management protocol, it is also easily possible to access the internal printer network via an external network 64 which is connected to the printer 52.
- LAN Local Area Network
- a so-called SNMP agent 66 is provided to control access to the internal components of printer 52.
- the SNMP agent 66 is connected to a system parameter manager (SPM) 68 via the internal network.
- SPM system parameter manager
- the system parameter manager 68 manages all printer parameters and control variables of a printing system. If the printing system contains, for example, two printers that print the same carrier material, a system parameter manager 68 is provided for these two printers, which manages at least the interdependent parameters of the two printers. The system parameter manager 68 preferably manages all parameters and setting values of the two printers. Dependent settings and parameters of the printing system 'are "coupled to by the system parameter manager 68 that an easy operation of the printing system is possible. The system parameter manager 68 then a comparison of the printer setting performs the first and the second printer.
- the fixing temperature of the second must Be adapted to fix the print image, which is generated with the aid of the second printer on the same carrier material, in order to avoid damage to the micro-toner of the first print image.
- the system parameter manager 68 of the first printer then defines the values of the control variables of the second printer and transfers them to the second printer.
- the first printer and the second printer preferably contain a so-called management information base, in which all control variables of the respective printer or of the entire printing system are stored.
- the system parameter manager 68 of the first printer then writes the new values to this management information base of the second printer.
- the system parameter manager 68 determines operating values and measured values for the first printer and writes them to the management information base of the first printer.
- the management information base is contained in the system parameter manager 68 in the printer 52 according to FIG. 4.
- the SNMP agent 66 controls the access to the system parameter manager 68. If an unauthorized control panel 70 is connected to the printer 52 via the network 64, the control panel 70 receives only access to released data, so-called public, via the SNMP agent 66 Data, and on further protected data, so-called protected data, wherein the control panel 70 can only read and not write to this protected data.
- the SNMP agent 66 does not allow the control panel 70 read or write access to internal control variables of function groups 72 to 80 of the printer 52 and to data stored in the memory area 82.
- the internal control variables of the function groups 72 to 80 and the data in the memory area 82 are also referred to as private data.
- the data transmission between the function groups 72 to 80 and the system parameter manager 78 takes place on the basis of the Simple Network Management Protocol (SNMP) using a pipe.
- the pipe is a connection-oriented communication channel between two processes, which is also referred to as a stream.
- Pipes generally connect independent processes that are not directly related to each other.
- the function groups 72 to 80, the SNMP agent 66 and the system parameter manager 68 are program modules which are processed using a data processing system of the printer 52, for example using a personal computer.
- a second control panel 84 is also connected to printer 52 via network 64.
- the control panel 84 contains a data processing system which, in addition to an operating system, processes a display program, a so-called browser program module. With the help of such a browser program module, graphic user interfaces in particular can be generated with the help of a hypertext or with the help of program code.
- the control panel 84 receives these hypertexts via the network 64 from the web server 54, which transmits at least some of the hypertexts to the control panel 84 that are stored in the memory area 56.
- the graphical user interface generated in this way contains in particular input and output fields and graphical function keys, the display values or their switching states of which are displayed with the help of data on the control panel 84, which are transmitted from the control panel with the aid of RMI communication, RMI (Remote Method Invocation).
- RMI Remote Method Invocation
- Java programming language
- Remote Procedure Call or the so-called Common Object Request Broker Architecture is used as a transport mechanism for RMI.
- the graphical elements of the graphical user interface are loaded by the web server 54, which are displayed using the control panel 84, the displayed and Data entered via the graphical user interface can be transmitted to and from the control panel server 58 using RMI.
- the control panel server 58 is also referred to as an RMI server.
- the control panel 84 is a client both for the control panel server 58 and for the web server 54.
- the internal control variables are accessed by the control panel 84 via the control panel server 58.
- the control panel server 58 is connected to the SNMP agent 66. As already described above, the control panel server 58 carries out authentication using authentication data 62.
- control panel server 58 After this authentication, which checks whether the control panel 84 or the control panel server 58 has rights to access the internal control variables and parameters, the control panel server 58 is given unrestricted access to the system parameter manager 68 by the SNMP agent 66.
- the control panel server thus has 58 Access to the public data, the protected data and the private data.
- the control panel 84 is arranged directly in the housing of the printer 52. Further similar control panels can also be arranged at a distance from the printer 52 and can also be provided for the simultaneous operation of several printers, similar to the printer 52. It is also possible to arrange a further control panel, similar to control panel 84, in a service control center of the printer manufacturer. If the network 64 is connected, for example, to a further network, in particular the World Wide Web of the Internet, the further control panel can also be arranged very far away from the printer 52. The further control panel must be connected to this World Wide Web only directly or via another network.
- a control panel 86 is also provided, which is contained in a printer application. Similar to the control panel 70, this control panel 86 is connected to the SNMP agent 66 via the network 64, the data transmission between the print server 86 and the SNMP agent 66 using a simple network management protocol (SNMP).
- SNMP simple network management protocol
- a control panel 84 for a printing system with the aid of a personal computer or another data processing system, without any special configuration or installation being necessary.
- the personal computer only has to contain any operating system and a browser program module for displaying hypertexts, the browser program module having to support the so-called Java applet and thereby communication using RMI.
- Java applet for displaying hypertexts
- almost all available personal computers currently meet these requirements.
- no special software is required to operate the control panel with the help of the data processing system, with the help of which the control panel 84 is implemented. All data required to generate the graphical user interface are provided by web server 54 and by control panel server 58.
- control panel 84 only has to be connected to a network 64, via which data can be transmitted to and from the web server 54 and to and from the control panel server 58 of the printer 52.
- control panel 84 can also be connected to a network other than the printer 52 if the two different networks are possibly connected to one another via a further network.
- control panel server 58 also contains the hypertext and further data for generation the graphical user interface on the control panel 84.
- the management information base is included in memory 60.
- the management information base contains data which are arranged in the same structure as the control units and functional units contained in the printer 52 are organized. The arrangement of the control variables and parameters is thus structured hierarchically just like the control and functional units of the printer 52.
- control and functional units are function groups 72 to 80, system parameter manager 68, SNMP agent 66 , Control panel server 58 and web server 54.
- the memory area 82 in which paper parameters are stored, is hierarchically subordinate to the function group 72, the parameters contained in the memory area 82 being subordinate to the function group 72.
- the hierarchical structure and names of the variables are thus stored in plain text in the management information base in the memory area 60 and are stored in the memory area 82.
- these can be displayed on the control panel 84 in a manner that is suitable for the viewer, e.g. for a service technician in a clear and understandable form, by displaying the plain text name and the value of the variables.
- the print server 86 accesses the SNMP agent 66 with the aid of a printer-specific interface, whereby the print server 86 can also access the so-called private data with the aid of authentication.
- Data transfer between control panel 70 and SNMP agents 66 is done using SNMP, but this control panel 70 does not support the printer-specific SNMP interface via the control panel server 58. As a result, the control panel 70 has no access to the private data.
- control panel server 58 With the aid of the arrangement shown in FIG. 4, it is possible for the control panel server 58 to have access to all function groups 72 to 80 and memory areas 60, 62 of the printer 52 and for the access rights of unauthorized control panels 70 to be restricted.
- the print server 86 is authorized and thus has access to the management information base of the printer 52, to the public data and protected data.
- the control panel 70 only has access to the management information base of the printer 52, the accesses generally being read and write accesses.
- FIG. 5 shows a section of the block diagram according to FIG. 4 with the control panel 84, the network 64, the control panel server 58, the data store 62, the SNMP agent 66 and the system parameter manager 68.
- the system parameter manager 68 checks whether the request comes from an authenticated unit, for example from an authenticated control panel 84, 86, the control panel server 58 or a function group 72.
- Each function group 72 to 80, the servers 54, 58, the SNMP agent 66 and the control panels 70, 84, 86 are each assigned at least one network address, for example an IP address.
- the system parameter manager 68 analyzes which control panel 84, 86, 70 or which control panel server 58 the respective read - and / or write access takes place, the system parameter manager 68 depending on the presetting the access rights of the respective limited control panel 70, 84, 86 and / or the control panel server 58.

Rather, only one user interface for both printers 126, 128 is output on the control panel for setting the parameters of the carrier material, the entered setting values then being used for printer 126 and printer 128. With other setting values, such as the fixing temperature, dependent parameters or influencing parameters are then changed depending on the settings of the printer 126 in the printer 128 in accordance with a default setting.
- the print image to be generated by the printer 128 is reduced. Due to the higher fixing temperature, there is a greater shrinkage of the carrier material when fixing in the printer 126, as a result of which the printed image generated by the printer 126 also coexists the carrier material shrinks. The print image subsequently generated by printer 128 must then be increased by the amount of
- Shrinkage of the carrier material can be reduced so that the print images of printer 128 and printer 126 are congruent with each other, i.e. are in register.
