Roland

The function is nearly there - I get the default printer

I have a generic text printer which is showing with an exclamation mark on the windows printers ie showing as error then it returns status =2 which is great

However my HP laserjet is showing on its screen out of paper ( I pulled the paper tray out ) - but the function still says ready - I tried putting the printer offline and it still says ready - even though there are several jobs in the queue

Any ideas ?

as always any help is truly appreciated.

Andrew

Great stuff Roland, very usefull!

Here is a window which I think will work, I am still testing. The case statement is meant to convert the value constants to a string.

forward
global type w_main from window
end type
type cb_process from commandbutton within w_main
end type
type cb_cancel from commandbutton within w_main
end type
type printer_info_6 from structure within w_main
end type
end forward

type printer_info_6 from structure
unsignedlong dwstatus
unsignedlong reserved
end type

global type w_main from window
integer width = 2098
integer height = 1460
boolean titlebar = true
string title = "Printer Status"
boolean controlmenu = true
long backcolor = 67108864
string icon = "AppIcon!"
boolean center = true
cb_process cb_process
cb_cancel cb_cancel
end type
global w_main w_main

Hi Andrew

I think you would need to make a windows API call,

try looking at this article https://docs.microsoft.com/en-us/windows/desktop/printdocs/printing-and-print-spooler-functions

Hope that helps
