printing.js test

Printer ip :
The print may only start once you reload the page (when it kills the connection).

Note (2020): the local network scanner below is something I quickly made in 2011, nowadays much better scanners exist (i.e. deducing the local network using WebRTC, etc).

printing.js documentation

Printing.js makes printing with javascript super easy.
With a few commands you can print out whatever you want. It doesn't (yet) include all printer functions, but its not hard to use functions that are not in this library.
Example of a printjob:
<script type="text/javascript" src="printing.js"></script> <script type="text/javascript"> var printer1 = "192.168.2.2"; var printer2 = "192.168.2.99"; function print_ad(){ var haha = new print_job(); //Create a new print job haha.add_text_nl("Hello World!"); //Print text and a new line haha.add_text_nl("Printed directly from printing.js!"); //The same as above haha.set_box_pattern(6); //Set the box pattern to six haha.print_box(200,200,3); //Print a box, 200x200 points, //and use a Cross-hatch pattern to fill haha.add_postscript(psfile); //Print psfile defined in postscript.js haha.end_job(); //End the job haha.print(printer1); //Print the job on printer1 (192.168.2.2) haha.print(printer2); //Print the job on printer2 (192.168.2.99) } print_ad(); </script>

`print(ip)`	1	Possibly the most important function, print the data you set so far	`print_obj.print("192.168.2.56");`

Postscript

To print Postscript the best thing is to create a separate js file were you apoint the postscript data to a variable (a string).
Then add it to the print data using print_obj.add_postscript(psfile). Don't forget to escape it though! For example, replace / with \/, and " with \".
If you don't do this you will get problems.

Draw a box

If you want to draw a box, first choose your shade/pattern with set_box_pattern (if you need a shade/pattern).
The different kind of patterns that you can choose from (please ignore my cursor :)

Then, draw the box using print_box(height, width, filltype).
filltype can be any of the following:
0 - Solid area fill (black)
1 - Solid white area fill (white)
2 - Shading fill (using the shade you defined with set_box_pattern)
3 - Cross-hatch pattern fill (using the shade you defined with set_box_pattern)
4 - User-defined pattern (For this you need to look in the PCL guides of HP)
5 - Current pattern
