In a method for operating the print server, a spooling priority print job is determined which, among the spooling print jobs, has the highest printing priority and has not yet been stored in the print data cache memory. A print job size of the spooling priority print job is determined. A free capacity of the print data cache memory is also determined. One or more print jobs that are not currently being printed from the print data cache memory are deleted until the free capacity of the print data cache memory is equal to or greater than the size of the spooling priority print job, where the printing priority of the print job to be deleted is lower than the printing priority of the spooling priority print job. The spooling priority print job is then loaded into the print data cache memory.

The disclosure relates to a method for operating a computer for digital high-capacity printing systems to relay print data. The computer can include an operating system. Print data can be written to a memory and read from the memory to relay the read print data to be printed onto a recording medium at a printer. Operating system commands can be used for writing and reading. At least the operating system command for writing data can be supplemented by a delay function. The delay function can delay the operating system command for writing based on process identifier information. The process identifier information can describe a read process.

Method to operate a computer for digital high-capacity printing systems to relay print data

In a print server for digital high-capacity printing systems, print jobs are received, processed with predetermined application processes, and relayed to one or more printers. A method to operate the print server can include monitoring, using a collect trigger, status parameters which describe system statuses; and triggering, using trigger logic, filters to reading additional status parameters that include process statuses of application processes executed at the print server. The triggering of the filters can be based on whether the system statuses monitored with the collect trigger represent an extraordinary or abnormal operating status.

For optimized communication between two memory-related processes in a computer system, a synchronization function is coupled with an operating system function such that it withholds an output of an operating system message that signals a data end of a file in a memory region of the computer system. It can thus be avoided that a memory read process interrupts the reading of the file because a memory write process has not yet written all data of the file into the corresponding memory region.

For implementation of a transfer of data between two program elements, a buffer object is provided between and linking the program elements. One of the program elements writes data into the buffer and the other program element reads data from the buffer, thus driving data transfer. The program element writing the data causes the buffer to call the reading program element. The program element reading the data causes the buffer object to call the writing program element.

In a method or system for reception from a sender of a print data with a print job by a print server of a first printing system from a sender, with the print server of the first printing system acknowledging to the sender correct receipt of a predetermined data unit of print data according to a predetermined protocol. With the print server of the first printing system copying the print data to a mirror print server of a second printing system separate from the print server of the first printing system before execution of the respective acknowledgement for the predetermined data unit, and automatically using as a print server for continued execution of the print job given problems in storage of the print data on the print server of the first printing system, said mirror print server of the second printing system.

In a method or printing system for generation of document processing jobs, control parameters for the document processing jobs are read from different sources and stored in a control file. Priorities are associated with the sources. In the event specific control parameters are present in a plurality of the sources, control parameters from the sources that have a highest priority are stored in the control file.

In a method or printing system for sorting of print jobs, a check of specific directories as to whether a file belonging to a new print job has been generated is repeatedly implemented. A job identification number is associated with each new print job, the job identification numbers for print jobs stored in a specific group of directories being respectively generated chronologically. A plurality of print jobs are sorted corresponding to the job identification numbers.

In a method, a computer, and computer program modules to transfer data between servers of a computer network, a computer program module supplying the data from a first server is provided, and a reading computer program module is provided that reads the supplied data, and wherein one of the following transmission modes is selected:

The invention relates to a method for synchronizing program sections of a computer program. The program sections can run in parallel on different processors of a computer. Data transfer between the program sections is synchronized by providing a buffer. Unauthorized access to the buffer is prevented by means of a flag that is set automatically by buffer utilities. The data transfer between individual program sections is thus synchronized by the buffer synchronization class only, which consists of the buffer, internal variables and the buffer utilities, is configured in a very simple manner and can thus be tested in operation an in a relatively simple manner by means of a computer comprising several processors. The data transfer is very efficient as the individual utilities are designed in a simple and short manner and thus require little processing time and as the data can be directly written in or read out of the buffer.
