please give us a clearer description... post a screenshot, an example...
if you have troubles with english speak italian and I'll translate in the tracker for you.

ho un file di Calc con due fogli di calcolo, ciascuno con suddivisione della finestra (menù finestra –> dividi -> fissa)
imposto le aree di stampa una per ciascuno dei due fogli del file;
imposto, per ciascun foglio, che ci siano righe e colonne di intestazione che si ripetono (menù formato -> aree di stampa ->modifica)
salvo e chiudo il file;
riapro il file e l’area di stampa è stata salvata per intero soltanto nel primo dei due fogli di calcolo, mentre nel secondo foglio sono state salvate soltanto le righe e le colonne da ripetere e non l’area di stampa.

try uploading a test file with the features you are talking about.
It will be easier to replicate the issue.

once I have the file I'll prepare a proper english translation.

---

uploada qui un file con le caratteristiche di cui parli.
sarà più facile replicare il problema.

una volta visto il file cercherò di tradurre la tua segnalazione.

please tell if issue is still reproducible in current LibO 4.2.5.2 release

According to comment 3 and 4 setting as needinfo.

Seems like a duplicate of bug 55273.
