Routine Description:
OpenPrinter can open any of the following by specifying a string
in pPrinterName:-
Server
\\MachineName
NULL
Job
PrinterName, Job xxxx
Port
PortName, Port
Printer
PrinterName
ShareName
\\MachineName\PrinterName
\\MachineName\ShareName
PrinterName, UpgradeToken
ShareName, UpgradeToken
Note for Printer there are two Types
1 - Regular LocalPrinter
2 - DownLevel Connection Printer
For type 2 a LocalPrinter exists ( pIniPrinter ) but its port
does not have a monitor associated with it. In this case
we also open the port ( typically \\share\printer of a remote
machine ) before we return success.
GUI Applications usually use Server and Printer
Type Job and Port are used by Print Processors:-
A print processor will Open a Job then read the job using
ReadPrinter. A print processor will output to a Port by opening
the PortName, Port and using WritePrinter. Usually these strings
"PrinterName, Job xxx" "PortName, Port" are passed to the print
processor by the spooler and are currently not documented. We
do know that some OEMs have figured out the extentions and we
might break someone if we change them.
Type UpgradeToken is used by a Printer Driver:-
Used when we need to upgrade a printer's settings from an older
version of the driver to a newer one (see drvupgrd.c for details).
This was added in NT 3.51.
Arguments:
pPrinterName - PrinterName ( see above for different types of
PrinterName )
pPrinterHandle - Address to put hPrinter on Success
pDefaults - Optional, allows user to specify Datatype,
DevMode, DesiredAccess.
pIniSpooler - handle of spooler on which the open should occur.
( see SDK Online Help for full explanation )
Return Value:
TRUE - *pPrinterHandle will have a PrinterHandle
FALSE - use GetLastError
