Missing information by shared print

Hi, I have that problem with the print of document via shared printer.
The configuration of used computers and printer:
Print server- Windows Pro 8.1 - connected to the printer via TCP/IP port, driver PCL6
Client 1 - Windows 7 Home Premium SP1 x64 (driver x64)
Client 2 - Windows XP Home Edition SP2
Printer - RICOH Aficio MP 161
Network - Workgroup
Description of test:
1. I'm printing the document with 3 pages from client 1 (W7) on the shared printer. 
    On the queue window (W7) is displayed the number of pages 1, equally on server (W8)
2. I'm printing the document with 5 pages from client 2 (XP) on the shared printer. 
    On the queue window (W7) is displayed the number of pages 5, equally on server (W8)
The number of pages really printed on shared printer is correct of both clients.
If I use function GetJob (winspool.drv) on client 1 (W7)  and on print server (W8) too,
I get same result for the parameter "TotalPages", i.e. 1 page (W7) and 5 pages (XP)
I tried to set driver isolation or shared via Print Mangement on print server (W8)
but the result is same, i.e. the incorrect displayed number of pages which are printed
on client 1 (W7).
If I use local driver of same printer on client 1 (W7) the number of pages is correct.
It's possible to set the security of client with Windows 7 that display correct number of 
pages? Thank for your support.
