Try with debug mod disabled.
debug was disabled. (you mean the bug icon in the right uper corner?) i tried with debug mode enabled as well ... same behavior . Interesting was, that pdf creation was working from the dashboard plugin. i seems that ob_end_clean makes the pdf printing more stable in case that there is something in the buffer ...
Try with debug_mode disabled (always) and all plugins disabled.
same result. the system is centos 7 with remi 7.2 with remi 5.6 the problem was also there the productive system is more or less the same with c7 , glpi 9.1 and php 5.4 . there i dont have the problem.
here some sys infos

I cannot reproduce on 9.3 (tested on demo website and local).
hi "trasher"
i don't want you to reproduce this error and i don't need any help.
i just recommend to add an
ob_end_clean();
before every
$pdf->Output('glpi.pdf', 'I');
in any file where tcpdf is used by glpi , that's all.
ob_end_clean cleans the output buffer . So if some messages are in this buffer , tcpdf creates this error message ... and to avoid this errors it's recommended to use
ob_end_clean(); $pdf->Output('glpi.pdf', 'I');
instead of a simple
$pdf->Output('glpi.pdf', 'I');
see http://php.net/manual/en/function.ob-end-clean.php and https://stackoverflow.com/questions/16011050/tcpdf-error-some-data-has-already-been-output-cant-send-pdf-file
for some reasons under centos 7 and glpi 9.2 it's not working without ob_end_clean .
Thats work for me ! Thanks
Hi.
After update to 9.2 with new remi php i got the following error when i tried to save something as pdf
"TCPDF ERROR: Some data has already been output, can't send PDF file"
No PDF was created, just this error message.
found the solution here https://stackoverflow.com/questions/16011050/tcpdf-error-some-data-has-already-been-output-cant-send-pdf-file
with a grep i found
... and i added a line with "ob_end_clean();" before the lines with "pdf->output"
after adding this the problem was gone .
PS: just as an info ... the same i did with the glpi-pdf plugin. Maybe you can forward this to "remi" and "yllen" ... because this glpi-pdf plugin is not on github ... :-(
