Problem:
How do you set "Duplex Printing"? (printing on both sides of a page requires optional printer feature)
Resolution:
This will only work for a printer that acutally can print on 2 sides
Manual Duplexing does not work with this method
Using PC_PRINTER_DEFAULT_PROPERTIES.
The PCPDP example program demonstrates how to use the PC_PRINTER_DEFAULT_PROPERTIES routine. The routine requires two parameters, "flags" and "properties".
call 'PC_PRINTER_DEFAULT_PROPERTIES'
using by value flags
by reference properties
returning status-code
end-call
The "flags" parameter is an independent, numeric item passed by value. There are eleven predefined initialization values for this parameter, one for each of the printer properties that can be initialized. These values may be combined arithmetically. Combining values permits setting multiple properties with a single function call.

The "properties" parameter is a data record structure consisting of twelve elementary items. The first item specifies the overall "properties" record length. The other eleven items permit you to specify the options that you want used for the printer properties that you selected with the "flags" setting. The "properties" items that you are not setting should be initialized to NULL values.

The PCPDP program initializes the "properties record" length.
move length of properties to pr-len
Sets the flags for the "properties" that need to be adjusted.
move P-PRINTQUALITY to flags
add P-DUPLEX to flags
Enters the new values for the "properties".
move DMRES-HIGH to pr-printquality
move DMDUP-VERTICAL to pr-duplex
Calls the PC_PRINTER_DEFAULT_PROPERTIES routine.
call 'PC_PRINTER_DEFAULT_PROPERTIES'
using by value flags
by reference properties
returning status-code
end-call
And checks the status-code.
if status-code <> ZERO
move status-code to pENumber
call 'PrinterError'
stop run
end-if
It is important to understand that the PC_PRINTER_DEFAULT_PROPERTIES routine just saves the values that you set. These values do not get validated and used until you actually open a printer or attempt to print a file.
The PCPDP program includes a printer error table (PRNTERRW.CPY) and a routine that extracts and displays the error text from the table (PRNTERRP.CPY). The error message is displayed to the screen.
Included in the zip file is a Wordpad document named DEVMODE.doc. This is a copy of the Microsoft Win32 SDK documentation on the Device Mode data structure. You will notice the similarities in the Microsoft documentation and the Micro Focus documentation. If you haven't installed the Win32 SDK, it is located on the second CD provided with Net Express 3.1.
