hi i am very new to pd and am curious about the possibility of printing to a thermal printer , using the print object maybe? i am running pd on a rasperrypi and am an artist looking to make a work that prints something physically out of a printer at the same time that a sound is played .. not sure where else to start or get info on this so if anyone has any ideas or can point me in the right direction i would be very grateful! thanks!

@_m You might be able to use [print] which prints to the terminal window...... but redirect the output directly to the printer. I do not know of a Pd "external" that will simply do as you wish.
As Pd starts up it establishes communication with it's gui..... the terminal....
https://puredata.info/docs/developer/PdStartupOrder
and you could change the behaviour using the standard start-up flags....
http://puredata.info/docs/faq/commandline
and redirect output using the -stderr flag to stderr....... whence you could pipe it (redirect) directly to the printer.......
I know it works writing to a text file..... so it must work to the printer.
You will have to google for that.... I am not so familiar with Linux... but all os's are very similar, with slightly different syntax at the command level.

Or simply use the shell object and send it a simple "lp" command

[lp /home/pi/myfile.jpg(
I
[shell]

The issue in the printing raspberry pi 3 is also happening with most of the users as well and I am also one of them. I am not having access to printing that and the thing is that, it also shows Epson error code e-01 on doing the process.
