Details:

Ghostscript 9.26 in installed in /usr/bin (gs and ghostscript).
/usr/bin is on the path.
In Octave I get the following warning and error

>> surf(peaks)
>> print('peaks')
warning: print.m: Ghostscript binary is not available.  Only eps output is
possible
warning: called from
    __print_parse_opts__ at line 487 column 7
    print at line 416 column 8
error: __ghostscript__.m: Ghostscript binary is required for specified output
format, but binary is not available in PATH
error: called from
    __ghostscript__ at line 64 column 5
    __opengl_print__ at line 155 column 29
    print at line 710 column 16

Checking the path within Octave gives
>> system('echo $PATH')
/snap/octave/29/usr/sbin:/snap/octave/29/usr/bin:/snap/octave/29/sbin:/snap/octave/29/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/octave/29/libexec/octave/5.2.0/site/exec/x86_64-pc-linux-gnu:/snap/octave/29/libexec/octave/api-v53/site/exec/x86_64-pc-linux-gnu:/snap/octave/29/libexec/octave/site/exec/x86_64-pc-linux-gnu:/snap/octave/29/libexec/octave/5.2.0/exec/x86_64-pc-linux-gnu:/snap/octave/29/bin
ans = 0

which shows that /usr/bin is on the path.
