Customer is reporting VM exhausted errors when printing files to a
TurboLPS20 printer from a WNT 4.0 server. They are using an application
called ViewLogics that a prior version generated postscript files itself.
Now the latest version uses the generic postscript driver from NT 4.0 to
generate the code stream.
The customer has noticed that the postscript file sizes doubled
from the old to the new. Same drawing on B sized paper was ~1.5MB in
size from the old version of the application. Now using the NT driver
with the LPS20 PPD it is ~3.5MB.
I have tested the file on a Turbo20 with a postscript level I
interpreter and it causes the VM exhausted errors. When printer to a
Turbo20+ (level II interpreter) it will print.
The file is at NECSC::D_FSS:[harvey]bad.ps
If this was a W95 or WIN3.1 client, We would ask the customer to
select clear memory per page and conform to Adobe specs in the WIN3.1
driver or Optimize for portability for W95.
For the NT driver there is not much to change under the device
settings. Is there a clear memory per page, or Optimize the driver
features?

By "generic PostScript driver" do you mean the the PostScript printer
driver that comes with Windows NT 4.0, PSCRIPT, or some other "generic"
PostScript driver that Viewlogic added, or what? I assume that the
"turbo PrintServer 20 v48.3" driver that comes with Windows NT was used.
There are no generic panacea switches in the Windows NT driver,
nominally because it produces better PostScript. :-)
I assume that the VMOption (memory setting) has been set up to match
the amount of memory in the customer's PrintServer.

Tim,
Correct me if my understanding of the NT print system is wrong. :-)
NT has the generic postscript driver PSCRIPT.DLL, PSCRIPT.UID and its
associated help files. Our printer "drivers" are only PPD files that
setup the correct behavior for the particular printer.
NT has other generic driver files for PCL, plotter and others.
These generic drivers also use discriptor files to setup the behavior
for the printer/s.
The customer said that they had worked this problem with ViewLogic
and Viewlogic uses NTs generic driver. The customer has already tried
the idea of lowering the memory setting. They have used it at 800KB and
500KB with no help. Are there other items that can be modified in the
PPD for the printer to change the way the postscript stream is generated?
