What does this Error code mean ?

Error using checkArgsForHandleToPrint
Handle input argument contains nonhandle values.

Error in checkArgsForHandleToPrint

Error in print>LocalCreatePrintJob (line 100)
handles = checkArgsForHandleToPrint(0, varargin{:});

Error in print (line 38)
[pj, inputargs] = LocalCreatePrintJob(varargin{:});

Error in saveas (line 181)
        print( h, name, ['-d' dev{i}] )
Error in S_1 (line 200)
saveas(gcf, cell2mat(fileName),'jpg');

Error in MainScript (line 21)
S_1; clearvars;

Deep in the code of Matlab itself

Handle input argument contains non handle values

a nonhandle value was passed where a handle was expected. That in turn was caused by

Error in S_1 (line 200)
saveas(gcf, cell2mat(fileName),'jpg');

a saveas in your function, S_1, at line 200. Put a breakpoint at saveas and run the code. At the breakpoint inspect the values that are passed to saveas

K>> h = gcf
h = 
  Figure (1) with properties:
       
      Number: 1
        Name: ''
       Color: [0.9400 0.9400 0.9400]
    Position: [680 678 560 420]
       Units: 'pixels'
   
  Show all properties
K>>

et cetera

Thanks for your reply

This happens when I run few code in a batch. Out of 10 codes one give the error.

When I run it individually, no problem.

Set

dbstop if error

start a batch and at the "break" (when the error is about to occur) inspect the input values of saveas
