Definitions
- the invention relates to a method and apparatus for operating a thermal printer unit having a printhead and heating elements associated with the printhead.
- a print carrier For thermal printer units, a print carrier, z. As printing paper and the print head, which consists of a plurality of small heating elements, moved past each other.
- a distinction is essentially made between three printing techniques, direct thermal printing, thermal transfer printing and a thermal sublimation printing.
- thermo-sensitive print carrier In direct thermal printing, the print head is pressed directly onto a thermo-sensitive print carrier, which blackens when heated. This method is used, for example, in receipt, label or ticket printers.
- thermal transfer printing a special color foil is passed over the print carrier under the print head, which has hundreds of heating elements which transfer the print image. If a heating element is activated and heated, the color layer melts in the film and is transferred to the print carrier. This method is used, for example, in printers for control cabinet and device markings.
- thermo sublimation printing Similar to the thermal transfer printing is the thermal sublimation printing.
- wax evaporates and penetrates the print substrate. In this case, heating takes place to very high temperatures, whereby the wax is placed in a gaseous state and evaporated.
- It can also be multicolored expressions are transferred to the print carrier, with each printing ever only one color per Control can be applied.
- each (color) pixel must be precisely controlled up to four times the same print position in order to produce the desired color tone with the usual four standard printing inks, ie yellow, magenta, cyan and black.
- the thermo-sublimation pressure is used, for example, in photo printers.
- the thermal printer unit typically consists of the printhead and a print carrier advance unit.
- a microcontroller is used, which is designed to control the print head and the print carrier advance unit in accordance with a character to be printed.
- the heating elements associated with the print head are driven and heated in accordance with the character to be printed, and the print carrier is blackened, for example, by short-term direct contact with the heated heating elements.
- the print carrier advance unit is actuated and the print carrier is advanced accordingly and the next pixel line is printed according to the character to be printed.
- the control for the printhead programmed in the microcontroller converts the characters to be printed into a multiplicity of bit sequences, one and / or several bit sequences representing a row of pixels to be printed.
- the bit sequence consists of a number of bits, such. 288, which corresponds to the number of pixels per pixel row and / or the number of heaters in the printhead.
- the individual bits of the bit sequence correspond to the switching states of the corresponding bit sequence
- Heating elements corresponds to the switching state of a 1 of the respective bit a switched heating element and the switching state of a 0 of each bit a switched-off heating element in the print head.
- the microcontroller transmits to the thermal printer unit the bit sequences converted from the character to be printed, for example by means of a serial transmission, and starts the paging tion of the heating elements according to the currently valid bit sequence by means of pressure command signals. If, for example, a solid line across the width of the print carrier is to be transferred to the print carrier, each bit of the bit sequence is set to 1. After the transmission of the bit sequence to the thermal printer unit associated with the printhead heating elements are in accordance with the transmitted bit sequence by means of the print command signals briefly, such. B. 1 ms, turned on. In the switching state, in which all the print head associated heating elements are turned on, the thermal printer unit has a maximum power consumption, such. B. 8 A.
- Thermal printer units are used for example in digital tachographs. This type of tachograph and / or tachograph no longer uses a chart of paper to record the vehicle operating data, as conventionally used, but stores the vehicle operating data and driver data on an electronic medium. In an expanded version, thermal printer units are also used in tachographs and / or digital tachographs in order to transfer the currently valid vehicle operating data and driver data to a print carrier, if required.
- Digital tachographs are used for example in vehicles according to the Hazardous Goods Ordinance Road (GGVS), such. B. in tanker trucks.
- the digital tachographs are connected to the on-board network of the tank truck.

- a permanent voltage is applied, such. B. 24 V.
- This terminal may in certain types of registration of vehicles to GGVS only with a predetermined maximum current value, such. B. IA, be charged.
- At one of the ignition voltage circuit associated terminal for the connection of external devices, typically terminal 15, is located only when the ignition of the refueling vehicle is switched on a voltage which typically corresponds to that of the continuous-voltage circuit.
- a current maximum value specified for the terminal of the ignition voltage circuit is not specified in most cases.
- the digital tachograph is typically connected to the terminal of the permanent-voltage circuit and thus configured to record vehicle operating data reliably and at all times.
- the current requirement of the digital tachograph in all its available operating states must not exceed the current maximum value specified for the continuous voltage circuit.

If more than one group of heating elements to be controlled simultaneously is determined from the type of grouping, the groups are actuated offset in time from one another, wherein the heating elements of the respective group to be activated are controlled simultaneously when the group is actuated.

If the number of heating elements of the respective pixel row to be controlled is so small that only one group can be determined, then this group corresponds to the last group. In this type of grouping, particularly few groups are formed per pixel line to be printed, and thus the number of mutually offset actuations is considerably reduced, which leads to a particularly fast expression of the respective pixel line while limiting the power consumption.
- the heating elements of the respective pixel row are assigned to at least two blocks, one block comprising a number of at least two locally adjacent heating elements and each
- Group is assigned at least one block.
- a division of the heating elements into blocks allows a special flexible assignment of the heating elements to be controlled into corresponding groups.
- each group can also be assigned more than one block, which considerably reduces the number of time-offset group activations.
- the number of heating elements per block is dependent on the heating elements to be controlled per pixel row and the predetermined maximum number and each group are assigned to each associated block heating elements. This makes it possible to ensure a particularly simple control of the power consumption limit.
- the blocks per pixel row are combined into respective groups such that the resulting number of heating elements to be controlled simultaneously is less than or equal to the predetermined maximum number.
- the blocks per pixel row are combined into respective groups such that the resulting number of heating elements to be controlled simultaneously is less than or equal to the predetermined maximum number.
- the predetermined maximum number is determined as a function of a current maximum value with which a supply voltage source supplying the thermal printer unit may be loaded to the maximum.
- an additional supply voltage source and associated additional circuitry is not necessary. This expands the field of application of the thermal printer unit and enables particularly cost-effective operation.
- applications with thermal printer unit for example, in battery-powered applications or applications with special requirements, such as those according to GGVS.
- the predetermined maximum number is determined depending on an operating temperature of the thermal printer unit.
