This is a printing UDF which allows you to print text in any font, size and colour at any position on the page, draw lines, curves, elipses, pies in any colour, and print images. Useful for labels, re

Just want to update from a user's side: This dll & udf is still working in 2017 using Win 10 current releases and it still seems to me the best option for complex printing tasks handled by Au

Do you think any one will guess which link you mean ❓ Please use this feature:

I don't know why setting the paper size wasn't ever included in the udf, but if you still need this I will try to add something. If I don't see a reply over the next week then I will do nothing on the assumption that I am too late to help.

Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.

Hi Martin,

I use your DLL for a little project where we are printing some labels with the help of a brother label printer.

I create a QR code with createQRw.au3 and add some text to the right of it.

There are two things I still have a problem. First of all I would like (also) have the ability to set the paper size to a specific value so that the user hasn't to do so. Cause when the length of the label isn't right the QR code has not a square size and won't be recognized by our scanner.

The second thing is a problem I hope you have an idea. On some computers my script prints an empty second page and I don't know why. Even when the printer settings and the text to be printed and all computers are teh same. Do you have any hints for me Martin?

(I'am using the _PrintImage function. It also prints a second page when printing a tiny pic which fits into the page bounderies)

Is there an ability to force the printer to only print one page?


many thanks in advance Martin

I have been using this UDF, quite successfully, for some time, but I have found the following issues:

First, _PrintPageOrientation doesn't seem to have any effect, printing to PDF or to my Brother printer (HL-1850).
2nd, _PrintDllStart always fails if I previously do a screen capture with _ScreenCapture_CaptureWnd.

I am using Windows 7.

Here is sample code that illustrates these problems.

#include <ListViewConstants.au3>
#include <printMGv2.au3>
#include <ScreenCapture.au3>
#include <WindowsConstants.au3>
#include <GUIConstants.au3>
#include <GUIConstantsEx.au3>

Local $Frm1 = GUICreate("Test", 1200, 650, -1, -1)
Local $LVhdrs = " Rec. |Last|First"
Local $idListview = GUICtrlCreateListView($LVhdrs, 10, 10, 1200, 600, BitOR($GUI_SS_DEFAULT_LISTVIEW,$WS_VSCROLL))
GUICtrlSetBkColor(-1, 0xFFFFFF) ; 0xEAEAEA)
Local $idListview_Handle = GUICtrlGetHandle($idListview)
Local $btnSave = GUICtrlCreateButton("Save (Screen Capture)", 400, 620, 150, 22)
Local $btnPrint = GUICtrlCreateButton("Print", 600, 620, 150, 22)

Local $aLVRowID[20]

For $ii = 0 To UBound($aLVRowID)-1
    $aLVRowID[$ii] = GUICtrlCreateListViewItem($ii+1 & "|" & "Last Name " & $ii+1 & "|" & "First Name " & $ii+1, $idListview)
    GUICtrlSetBkColor(-1, 0xEBEBEB) ; 0xFCF6EA)


While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
        Case $btnSave
        Case $btnPrint

Func SaveImage($hHandle)

    Local $sFileName = FileSaveDialog("Save Screen Capture", @MyDocumentsDir, "(*.jpg;*.jpeg;*.bmp;*.tif;*.tiff)",  $FD_PROMPTOVERWRITE + $FD_PATHMUSTEXIST)
    If @error Then
        sleep (1000) ; give time for dialog to disappear before starting screen capture

    ;_ScreenCapture_SetJPGQuality(80) ; default is 100
    _ScreenCapture_CaptureWnd ($sFileName, $hHandle, 0, 0, -1, -1, False)
    ShellExecute($sFileName) ; display saved image using default viewer


Func PrintIt()
Local $msg

$hDll = _PrintDllStart($msg);this must always be called first
if $hDll < 1 then
    MsgBox(48,"Printer Error", "Error from dllstart = " & $msg)

Local $prnChoice = _PrintSetPrinter($hDll) ; opens choose printer dialogue
If $prnChoice = 0 Then


_PrintPageOrientation($hDll, 1) ;  0 = portrait, 1 = landscape *** DOESN'T SEEM TO WORK...

MsgBox(0,"","Now printing")

_PrintDllClose($hDll);this must always be called last

After further experimentation, it seems that the problem lies with the ScreenCapture UDF, not the Print UDF, as SQlite will also not start up after _ScreenCapture was invoked. However, this problem seems to occur only when running uncompiled script. Once compiled, it seems to work OK.

I've started trying to work with this again and I've noticed a new problem that I don't think has been reported: it ignores all printing defaults set in the printer properties and does some other defaults. I'm working with a label printer and I've set speed and density in the printing defaults, but this UDF just does whatever it wants. Am I missing something?

Hi, Martin

I found a need for this UDF yesterday. I needed to create a way of making a page of small labels (to price things I will be selling). I got it working just fine and THANK YOU FOR MAKING THIS UDF, IT HELPED ME TREMENDOUSLY! I did find a couple interesting complications that I didn't expect. I thought I should mention them, not sure if they are noteworthy.

1. I tried to make a GUI with Koda using pixels to space plan the sheet. However, the pixel numbers for the GUI didn't line up with the pixel spacing with your UDF (I assume it has to do with DPI, not GUI pixels). I had to use the good old trial-and-error method to get the correct font size, bold setting and spacing on the x and y axis. But after about 30 pieces of paper (small price to pay🤑), I got it perfect. My final product looks very professional. Am I correct about the DPI vs. pixels theory?

2. My initial runs were scripted with a simple .au3 file. Later, I converted that .au3 file into a function. I ran into all kinds of crashes, errors or nothing happening. I tried to pass variables into the function or make them global, but I couldn't make the function work. My best solution was to make an independent .exe (using your same UDF) for the final print phase and have it read the data from a .txt file. Using your UDF as a standalone file reading data, it works great. But I had lots of problems using it inside a function. The problem was probably my code, but I got it working, so I'm happy. Edit: Tonight, I was re-working some of the code and discovered exactly what my problem here was. The independent .exe was compiled as 32-bit (to be compatible with the .dll). When I run the code as an .au3, AutoIt runs scripts 64-bit by default (I chose this when installing AutoIt). Compiling the separate script works very well.

Thanks again! I really love this UDF! If it weren't for this UDF, I would still be manually typing up every label in MS Word (very tedious).

print to pdf file

does not print yellow. Why?

#include <printMGv2.au3>

_TextToPrint('CutePDF Writer')

Func _TextToPrint($sNamePrint)
    Local $aTextP = FileReadToArray(@ScriptDir & '\text.txt')
    Local $hOD = _PrintDllStart()
    _PrintSelectPrinter($hOD, $sNamePrint)
    _PrintPageOrientation($hOD, 1)
    Local $y = 60, $iC = 0
    Local $aCol[4] = [0xFF0000, 0x0000FF, 0xFFFF00, 0x000000];blue red yellow black
    For $n = 0 To UBound($aTextP) - 1
        If $iC = 4 Then $iC = 0
        _PrintSetFont($hOD, 'Courier', 12, $aCol[$iC])
        $iC += 1
        _PrintText($hOD, $aTextP[$n], 35, $y)
        $y += 43
EndFunc   ;==>_TextToPrint

This is a printing UDF which allows you to print text in any font, size and colour at any position on the page, draw lines, curves, elipses, pies in any colour, and print images. Useful for labels, reports, graphs and standard forms. Can also print barcodes. It uses my printmg.dll. It is not intended to do the sorts of thing you can do with the Word UDF by big_daddy.

Note the dll is 32 bit and so only works with 32 bit applications.

printout from the code in the example in the download.

Functions available are -
Start using/Finish using the UDF
_PrintDllStart _PrintDllClose
_PrintVersion - Returns version of UDF or dll
Printer control
Printer selection, getting & setting parameters
_PrintListPrinters - lists all installed printers
_PrintSetPrinter - manual printer selection dialogue
_PrintSelectPrinter - programmatically set the printer.
_PrintPageOrientation - set portrait or landsacpe
Text printing
_PrintSetFont - Font, size, attributes and colour
_PrintText - At x,y and angle.
_PrintSetBrushCol - sets the colour used for filling
_PrintEllipse - Filled ellipse or circle
_PrintPie - for filled pie slice
_PrintArc - Elliptical or circular arcs
_PrintRectangle - filled rectangle
_PrintImage - prints jpg, bmp and ico files (Has problems with some icons bigger than 64 x 64)

Latest change = 25th February 2011
Added example to the download which was missing.
