Here's a bit of code that allows to output the stage content  into the default Printer device. This implementation will do so without prompting a dialog window. The program was tested on a winxp manchine with processing V91.

my guess is that it's more to do with how the java printing api works.. i haven't looked at the most recent version of the code but you should make sure you're paying attention to printer margins (not paper size) and do some reading about how device coordinates are mapped between the screen and the printer in java2d.

Has anyone expanded this successfully?  I'm trying to print directly to the printer as well.

Hi,

We are trying to printout the stage with pitaru's printer_output.zip but the printed text has a very low resolution.

We tried to make create font with an higher size ( like 150 instead of default 48 ), we tried to work with some java code trying to change the printer resolution but we couldn't...


How is it possible to printout the fonts with a better print resolution?

We are working with mac OS 10.3.9 on a G4, printing with a HP_LaserJet_2200.

Thank you.

Hi,

we are still trying to print-out with processing.
we can not use pdf because we would like to print-out directly from an application.

we also tried seltar's code: it works but prints have half the size as the image data... and we couldn't find where to correct it.    

does anyone know how to solve the size problem?
thanks a lot. asli

this doesn't seem to work with opengl on a mac.

has anybody figured out something to print out opengl sketches?

Is it possible to print a jpg, that I saved in my sketch folder, direcly from my app. ?

I just tried the code from seltar.
It work!. It does a print job, but everything is turend out very black.
If I save the frame with the "saveFrame() cammand" it looks pretty good. But if i save it like the print (with bufferimage) It has the same black color as the prints.
I also tried to print the "savedFrame() version" but then it also turend out black.
(note; not just black, I can see my image a littlebit.)


I'm trying to make a kind of "photobooth machine" for a school project.
I just startet a week ago with progressing so it's like chinees for me.
A already 'figured' some things out.

PhiLho if you have time to take a look at it and maybe make some improvements.
