Build a new main class, updated the parser to be more robust for framing commands from a live host device connected to a serial port.
- Allow rescan for serial ports on certain gui events to account for plugging/unplugging of devices. Also detect if no ports are found and prompt for scan.
- Parser fix to improve handling of rejected chars
- Always output port status if one is open
Note: At higher serial port speeds, the simulator may receive some garbage characters at the start of the speed handshake as the fw tries commands at lower serial speeds, those can still be read with inconsistent bytes. In testing so far, the parser has always recovered.
In general, 9600 baud, the first handshake speed the firmware attempts shows a clean "provisioning receipt". If the usb-serial or serial device is connected to the application while powered 9600 might show some garbage too. This has not been seen to cause test failure conditions.
The application can run continuously between testing devices without a need to restart it, or even reopen/close the port. This means you can open the port at a given speed, plug in a Cord, power it holding down the button to get into provision mode, and watch the test results, then unplug and plug in the next unit. Clicking clear might be desired in between so not confuse between outputs of one unit vs another.
- Parser fixes to recognize two byte cut commands
- Added test for cut command on provision
- Added test for unintended echo replies
Parser fixes for unprintable characters
Added a new gui panel with controls changes for testing.
The build will create a jar file: ./build/libs/copper-cord-print-tester-x.y.jar
The program should be runnable via java -jar copper-cord-print-tester-x.y.jar
The Gui panels and as well as the new Copper specific dialog was laid out w/ the netbeans IDE
A gradle build config was added, allowing command line builds
gradle build : will build the jar file gradle run : will build and run the tester
ESC/POS Printer simulator written in Java.
This provide Swing GUI to display receipts and also write content to a file - access through web url.
The idea comes from JavaPos printer simulator and from escpos-tools, a PHP library.
Web access:
java -jar ESCPosPrinterSimulator.jar [port] [filepath] [filesize]
Example:
java -jar ESCPosPrinterSimulator.jar
java -jar ESCPosPrinterSimulator.jar 9100
java -jar ESCPosPrinterSimulator.jar 9100 receipts.txt 10
run as linux / ubuntu background:
java -jar ESCPosPrinterSimulator.jar 9100 receipts.txt 200 & exit
Arguments:
- port: optional - default 9100.
- filepath: path to the written receipt - if available, program will run without GUI.
- filesize: in KB - default 200. If reach the size, file will be deleted then recreated.
Deploy on linux Apache & PHP
java -jar ESCPosPrinterSimulator.jar 9100 /var/www/html/escpos-printer/tmp/9100.txt & exit
access through url:
http://{ip}/escpos-printer/printer-page.php?files=9100.txt
