How to use print in a parfor

Whenever I am using print inside a parfor, I get some all black images. How do I fix this?
Here is a snippet of code and I attached the variables figs and output_files (I had to make them way smaller to upload).
Thanks!!
load('variables.mat')
% output resolution and format
outputDPI = '-r900';
outputFmt = '-dpng';
parfor f = 1:numel(figs)
figure1 = figs{f};
output_file = output_files{f};
if ~isempty(figure1)
opengl software
set(groot, 'DefaultFigureRenderer', 'painters');
print(figure1, output_file, outputFmt, outputDPI);
close(figure1);
end %if ~isempty(figure1)
end %for f = 1:numel(figs)

I am getting this error when using parfor
Error using print
Functionality not supported with figures created with the uifigure function.
and this error when using for
Error using checkArgsForHandleToPrint
Handle input argument contains nonhandle values.
Error in checkArgsForHandleToPrint
Error in print>LocalCreatePrintJob (line 101)
handles = checkArgsForHandleToPrint(0, varargin{:});
Error in print (line 38)
[pj, inputargs] = LocalCreatePrintJob(varargin{:});
In any case, would just running this in serial work out? Or are you trying to speed up the rendering?

WIth your actual data file, please execute
cellfun(@(C) isprop(C,'isUIFigure'), figs)
and see if some of them show up as 1 . Any entries that show up as 1 correspond to uifigures -- uifigure have that property but traditional figure do not have that property.
