AST-PCNET PRINT SPOOLER
|
||
|
||
|
||
When using the AST-PCnet Print Spooler on a local PC (shared
|
||
printer attached), under certain conditions the SuperSpool
|
||
secondary control commands (/P, /C /S, etc.) will not work. The
|
||
specific conditions which cause this problem are as follows:
|
||
|
||
1. The system board switches are set for less memory than
|
||
is actually installed in the computer.
|
||
|
||
2. SuperSpool version 1.31, is resident in the area of
|
||
memory located above the setting of the system board
|
||
switches.
|
||
|
||
3. A SPLLINK version 1.00 command for local PCs has been
|
||
executed.
|
||
|
||
Under these conditions, attempting to use a SuperSpool secondary
|
||
command such as "SUPERSPL /P" will result in the following error
|
||
mesage:
|
||
|
||
Printer Specification Required.
|
||
ABORTING...
|
||
|
||
This is caused by the fact that SPLLINK has "stolen" SuperSpool's
|
||
INT 17 interrupt vector, coupled with the fact that SuperSpool is
|
||
unable to locate its own "footprint" in low memory. It therefore
|
||
assumes that it is not resident and rejects the secondary
|
||
command.
|
||
|
||
If the user`s system is configured with more memory than the
|
||
system switches indicate and he needs to use the SuperSpool
|
||
secondary commands, the SuperSpool "/DH" and/or "/DNC" options
|
||
should be used when invoking SuperSpool the first time. This
|
||
will restrict SuperSpool to using only the memory located below
|
||
the system board switches, and the problem will not occur.
|
||
|
||
Note that the problem described above does not occur if you are
|
||
not using SPLLINK.
