S. Berenisker's code uses EnumJobs function to return the number of job.

Declare Integer EnumJobs in WinSpool.Drv as WS_EnumJobs ;
Integer hPrinter, ;
Integer FirstJob, ;
Integer NoJobs, ;
Integer Level, ;
String @pJob, ;
Integer cbBuf, ;
Integer @pcbNeeded, ;
Integer @pcReturned
*****
the 4th parameter of this function is LEVEL. this will take the value 1.
The Level parameter passed in tells the API which kind of structure you want returned.

this is the structure of level 1

***** VB CODE to return the number of copies.

'\\ JOB_INFO_1 - Standard print job info
Private Type JOB_INFO_1

lpPrinterName As String
lpMachinename As String
lpUserName As String
lpDocumentName As String
lpDataType As String
lpStatus As String

Dim lRet As Long
Dim pcbSizeRequired As Long, pcbBytesReturned As Long
Dim buffer() As Long

ReDim Preserve buffer(0) As Long '\\ Allocate a 1 byte buffer

lRet = EnumJobs(mhPrinter, 0, 255, 1, buffer(0), UBound(buffer), pcbSizeRequired, pcbBytesReturned)

'\\ Need to resize our array to cope with this data
ReDim Preserve buffer(0 To (pcbSizeRequired / 4) + 3) As Long
lRet = EnumJobs(mhPrinter, 0, 255, 1, buffer(0), UBound(buffer) * 4, pcbSizeRequired, pcbBytesReturned)

Dim pJobId As Long
Dim JobIds() As Long

For pJobId = 0 To (pcbBytesReturned - 1)
Redim Preserve JobIds(pJobId) As Long
JobIds(pJobId) = buffer(pJobId * 16)
Next pJobId


Private Declare Function GetJob Lib "winspool.drv" Alias "GetJobA" _
(ByVal hPrinter As Long, _
ByVal JobId As Long, _
ByVal Level As Long, _
buffer As Long, _
ByVal pbSize As Long, _
pbSizeNeeded As Long) As Long

This takes the JobId as returned by the call to EnumJobs and returns the level 1 structure filled with the details of that queued print job.
