WORKWORK - There is a problem here. It seems that
|
|
the graphics engine deletes the print job
|
|
once it is done playing it. Because of this,
|
|
only one copy is spit out. One fix would be to copy
|
|
the file off if we will be doing copies, then copy it
|
|
back for each copy. Another would be to add a flag to
|
|
the play call specifying whether to delete the file
|
|
or not. Finally, we could just not support copies
|
|
for journal jobs.
|
|
|
|
|
|
WORKWORK - GdiPlayEMF supports a call back function to
|
|
query which pages should be played next. This requires
|
|
support fromt the spooler to allow random access to the
|
|
spool file on a per page basis. When this is implemented
|
|
we can print any number of copies we like using this call
|
|
back function.
