MATLAB: Unable to change default printer using printopt

accessdeniededitMATLABprintprintingprintopt

Attempting to edit the "printopt.m" file results in an "Access denied" dialog. How can I edit this file on Windows 10?

Best Answer

Files installed on the default MATLAB path by MATLAB may require permissions to access. Access to this file requires administrator permissions. Try running MATLAB as admin and then editing the function.

Alternatively you could delete the "printopt.M" file from the default location and move it elsewhere. If using this method, be sure to add the new file to the MATLAB path. More information about adding files to the MATLAB path can be found at:

MATLAB: Can’t I open the PDF file generated using the ‘print’ function with default printer ‘Microsoft Print to PDF’

Specifying the format flag as '-dpdf' resolves the issue.

figure()
plot([0 1])
xlabel('Test')
ylabel('Test')
filename = 'Test.pdf';
if exist(filename,'file')
    delete(filename)
end
print('-PMicrosoft Print to PDF',filename,'-dpdf')

MATLAB: How to move the ‘pathdef.m’ file from its default location to another location in MATLAB 8.1 (R2013a)

The ability to select an arbitrary location for the MATLAB path file 'pathdef.m' is not available in MATLAB 8.1 (R2013a). One possible workaround is detailed below.

By default, the 'pathdef.m' file may be located in either the '$MATLABROOT/toolbox/local' directory or the '$USERPATH' directory, where $MATLABROOT and $USERPATH are the directories displayed after entering the commands

matlabroot

and

userpath

at the MATLAB command line respectively.

The 'pathdef.m' file can be manually copied from either of these directories and placed in an arbitrary directory. To use the copied 'pathdef.m' file at initialization, create a MATLAB file titled 'startup.m' and place it in the '$USERPATH' directory. Copy the lines of code below to the file. If a 'startup.m' file already exists in '$USERPATH', add the lines of code to the end of the file:

% save starting directory
startdir = pwd ;
% specify arbitrary directory containing pathdef.m
pathdir = '<MODIFY>' ;
% change directory so that target 'pathdef.m' has highest precedence
% in the MATLAB search path
cd(pathdir)
% set the MATLAB search path using PATH
path(pathdef)
% change directory back to the starting directory
cd(startdir)

Make sure to modify the string marked "MODIFY" in the above code to the directory to which the 'pathdef.m' file was copied. The 'startup.m' script will be automatically executed upon MATLAB initialization.
