If the PostScript printer driver is configured to use more than 32767 KB of memory, and you reset the Available PostScript Memory value to more than 32767 KB on the Device Settings tab, the PostScript printer driver UI continues to display the default minimum setting of 256 KB.

To workaround this behavior:

1. Use the Registry Editor to navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Printers\<PrinterName>\PrinterDriverData.

2. Double-click the FreeMem Value Name, a REG_DWORD data type, and set the data value to a number supported by the PostScript Printer driver, using the Decimal radix.

3. Press OK.

4. Exit the Registry Editor.
