Target.
Develop a hardware and software complex for converting and printing data from analyzers on a modern laser printer.
Introduction.
Analyzers are designed to perform laboratory tests, print results on a matrix printer connected via a COM port. To facilitate the issuance of results, it is proposed to create a module for optimizing data, forming them according to a preset template with subsequent output to a laser printer.
Hardware requirements.
The A. module has USB and COM ports.
B. The module is built on the basis of a single board computer using an open non-licensable operating system.
C. The module, if necessary, connect to a personal computer/laptop to configure the software through any available interface (preferably a LAN).
D. When power is turned on, the module must be loaded and put into operating mode without additional manipulations.
The E. module should support most modern laser printers from well-known manufacturers.
The printer must connect to the module via a USB port.
G. The analyzer must connect to the module via Com port (25pin).
The H. module should be easily duplicated.
I. The module should have the simplest protection against running the software part on a duplicate - the activation key / password.
Requirements for the program part.
A. PPDS data exchange protocol (ESC/P)
B. The program must receive data so that no print assignment remains in the analyzer’s memory after sending it to the module.
C. The program must automatically clear the printing queue (buffer) to the laser printer if a failure occurs when trying to print (autocleaning when power is turned off).
D. The program must allow you to configure the templates for printing data.
I. Pre-established type of analyzer: biochemistry or immunochemistry.
Types of templates: patient form, laboratory report, printing of calibration results, printing of quality control data (all data are text).
E. The program must have a customizable Russifier – an editable file for matching a set of letters in Latin to Russian expressions (Russian names for English abbreviated names of analyzes).
F.The program must convert data to established templates depending on the type of data transmitted (if necessary, change the location on the sheet), Russify with a pre-installed Russifier, add static inscriptions on the template.
