The purpose of printcal is to linearize the printer, nor to bring the printer 
to the "curved" state. So, Your printer will be closer each to other only if 
the calibration is applied to both, nor only to the second. The second printer 
recalibration result is the linearized behavior of the first printer.

If You print the test on the first printer with linearization (for first), the 
printers will match.
IMHO, current printcal can't perform Your task.
