How can I print multiple variables using printf

I am trying get printf to output multiple variables on a single line.

Having difficultly with argument handling and formats for printf and receiving unexpected results.

Code snippet

printf '%s %s %s' $infile $insize $indate 2>&1 | tee -a $logfile
find $infile -printf ' %p %s %CY-%Cm-%Cd %CH:%CM:%.2TS \n' 2>&1 | tee -a $logfile

Unexpected result
* first file size not showing, date and time not correct (printf)
* second file size correct, date and time not correct (find -printf)

Expected result

ftp://ftp.ncbi.nlm.nih.gov/pub/README.ftp 2037 2015-08-12 15:47:26 ./README.ftp 2037 2019-08-24 20:32:53

Thanks in advance.

Solution

printf '%s %d %s' "$infile" "$insize" "$indate" 2>&1 | tee -a "$logfile"
find "$infile" -printf ' %p %s %CY-%Cm-%Cd %CH:%CM:%.2TS \n' 2>&1 | tee -a "$logfile"

Result
