Possibly, but not via printui.dll.
I thought I'd point out that the text in BoBo's original post can be reproduced (in your current language) by typing this at a command prompt:
| Code: | | rundll32 printui.dll,PrintUIEntry /? |
Edit: Here's my first attempt at reporting printer status:
| Code: | DllCall("LoadLibrary","str","winspool.drv")
if ! DllCall("winspool.drv\OpenPrinterA","str","HP PSC 750xi","uint*",hPrinter,"uint",0)
{
MsgBox OpenPrinter failed.`nErrorLevel: %ErrorLevel%`nLastError: %A_LastError%
return
}
DllCall("winspool.drv\GetPrinterA","uint",hPrinter,"uint",2,"uint",0,"uint",0,"uint*",req)
if (A_LastError = 122)
{ ; ERROR_INSUFFICIENT_BUFFER
VarSetCapacity(pi,req)
if DllCall("winspool.drv\GetPrinterA","uint",hPrinter,"uint",2,"uint",&pi,"uint",req,"uint*",req)
Status := NumGet(pi,72)
}
if Status =
MsgBox GetPrinter failed.`nErrorLevel: %ErrorLevel%`nLastError: %A_LastError%
DllCall("winspool.drv\ClosePrinter","uint",hPrinter)
MsgBox % Status
/*

It works... but requires the printer name to be specified, and seems to only report PRINTER_STATUS_ERROR.

Specifying "uint",0 for the printer name (in OpenPrinter) gets the local print server, but calling GetPrinter on the returned handle seems to always result in ERROR_INVALID_LEVEL.
You might like to try getting the status of the current print job, as described in How to get the status of a printer and a print job. |
