printing option

[rudyboy]

Hi everyone,

Is it possible programatically to check if the printer that I will be used for printing is turned on? can you show me a sample code.

Second, my system will print on 2 kinds of printer; dot matrix and laserjet. Programatically, can i force powerbuilder to print a report to a dot matrix or laserjet?How can I do this?

Thanks

Some ways for doing that:
-If the printer is in a Port (LPT or COM) you can try write to them and check the result.
Example:
FileOpen( "LPT1",StreamMode!,Write!,Shared!)
check the return value for success or unsuccess
See also PrintGetPrinter ( ) for printer ports

-You can see also if the printer as a way to access his properties (in the printer manual).

-You can also search for driver use for thar purpose (I don't know how to do that).
This is reasonable if you use just 2 kind of printers. For n different printer, problably, you have n different ways to check that (I think...).

-Another solution is use the Powerwhizz printer utility (

http://www.powerwhizz.com/).

See the site for details.

-Check also the GetPrinter() API function.


For the second question I don't know if that is possible, unless you can access the printer properties (with one of the previous solutions...)


Hope that helped
