Agile APM XES to PCL
AGILE Print Manager
APM is installed and executed on a single dedicated PC running under any of the Microsoft Windows 95/98/2000/NT operating systems.
APM PC hardware consists of a PC tower with hard drive, 3.5-inch floppy, and a network interface card appropriate to the LAN to which it is connected at minimum. No keyboard or display is required for normal use, but may be used for configuration and monitoring functions. An uninterruptable power supply is recommended.
APM appears to be one or more virtual, or "logical", printers or LAN print queues to other elements of the LAN. Each virtual printer accept data as if it were an actual printer. APM utilizes selected filter programs to process each data stream, and then sends the translated data to the specified physical printer or print queue on the network. APM makes the printing of data streams intended for otherwise incompatible printers possible, and does this without requiring user intervention or rewriting of legacy code.
Each APM virtual printer is individually defined to other elements of the LAN (whether client, other print server, gateway, or LAN print queue) as if they were actual printers and is a complete software emulation of that printer in order to satisfy print job handling protocols for the data sent to APM. This allows normal LAN protocol processing, appropriate error handling, and user notification for stalled and abended jobs at the actual target printer.
Data sent to a selected APM virtual printer may contain data and commands intended for a printer type with a feature set that is not compatible with the actual physical printer. APM selectively converts the data to be compatible with the target printer.
Data and command filters may be specified for each virtual printer to correspond with the actual physical printer that the translated data is sent to. These filter and target printer assignments are made during configuration.
The actual target, or physical, printers are printers, print servers, or LAN print queues that are physically attached to and defined on the LAN. These are the printers that will actually print the data processed by APM. Any printers attached directly to the PC on which APM is resident and running may be accessed in this manner also.
APM may be configured either by executing a local configuration program on the APM PC or from a remote manager program on another PC attached to the LAN. Both the local and remote manager functions will allow real time monitoring of APM functions and various diagnostics. The diagnostics have two levels: Administrative and User. Users may view and control their print jobs, while Administrators can configure the system.
Configurations can be saved to, and restored from, a floppy disk or other archival medium.
XES/UDK to PCL translation is fully supported by APM and allows for legacy applications that output XES data streams for Xerox printers that are no longer available or supported to print on newer printers. APM allows these applications to be used without expensive or impossible changes being made to them.
Target Printers Supported
Configuration is simple and consists of: setting the APM PC IP address; definition of printer type for each virtual printer port; assignment of a filter to each virtual printer port; and selection of actual target printer queue on the LAN to which the data streams are directed after processing.
Note that while the data stream processing sequence requires that each virtual printer may have no more than one filter and only one target printer assigned to it, a target printer may have any quantity of virtual printers and filters assigned to it. Filters may be called as needed to process data: multiple copies of any filter may be simultaneously running.
All configuration changes take effect when selected or after end of job, as appropriate.
