Problem for report printing's color

[colintis]

I have a simple database to print reports in the company, but the default setting for the printer seems different. The printer's default setting will print all pages in black and white, even the reports don't have any colors as well.

When a print button is clicked, the procedure automatically changed to print in color; because a login is required if the quality is set to color in the company printer. I have no idea why only this database will do this itself. The VBA code for the button is as follows:

Private Sub cmdPrint_Click()
On Error GoTo Err_cmdPrint_Click

    Dim stDocName As String

    If frameStyle.Value = 1 Then
    
        stDocName = "Washout1"
        
    ElseIf frameStyle.Value = 2 Then
    
        stDocName = "Washout"
    
    End If
    
    DoCmd.OpenReport stDocName, acViewNormal

Exit_cmdPrint_Click:
    Exit Sub

Err_cmdPrint_Click:
    MsgBox Err.Description
    Resume Exit_cmdPrint_Click
    
End Sub

I had made a bit of work around to print the report in a semi-auto way: open report -> open print dialog -> print -> close report.

    DoCmd.OpenReport stDocName, acViewPreview
    DoCmd.RunCommand acCmdPrint
    DoCmd.Close acReport, stDocName

From the print dialog, I found the database itself changes the setting print quality from "Black and White" to "Colour", this doesn't happen to any other databases I worked on, only particularly this one.
