Hi Alexis,

1) Which OS are you using for it?
2) Do the versions of ADK and VStudio match?
3) Could you please try to generate PDFs from ADK and VStudio? Are they different, too?

is on windows 10

i have to check version

i am using 7.2v
is on windows 7 pro 64bits
Yes same version XOJO ADK and Valentina Studio and after print the BarCode i try to scan with a barcode scanner and no recognised the barcode i am using code 128

1. So it is always printed smaller from Xojo?
2. Can't recognise barcode printed even from VStudio?

yes Sergey
barcode scanner no recognise even from VStudio

i have to test other barcode scanner to see but it read perfect from any product barcode

this is my project

sorry
but my customer is waiting for me for finish my project

About wrong 128 barcode - yes, it looks like it is incomplete, we'll check&fix it ASAP

Please attach how you send it to the printer. Which parameters do you set for PrintToLocalPrinter?

The width is too small to fit this barcode.
And width depends on the length of the word - the longer the word, the bigger this code is.

Is it possible to use IDs of fixed widths?

mReport.PrintToLocalPrinter("ZEBRA LP 2443", "paper=BarCode,copies=" + Str(PageCount) + ""

what is the best BarCode other than code 128

RepStrConn="postgresql://host='" + vServerIP + "' port='5432' dbname='" + vServerDbName + "' user='postgres' password='home@2011'"

SqlStr01=" select itemnum,saleprice,qtylabel from barcodeprint where itemnum='" + BarLine + "'"


mprojectPath = GetFolderItem( "OrdenCompras.vsp" )

mProject = new VProject(mprojectPath)

try
mProject.Open()
catch e as VException
dim errNumber as Integer = e.ErrorNumber
dim errString as String = e.Message
MsgBox errString
end

if mProject <> nil then
vCounts = mProject.ReportCount()
end if

try
mReport = mProject.MakeNewReport("PrnBarCode", RepStrConn,SqlStr01 )
mReport.SetParameterValue("param1",Str(ActiveCajaReg))
catch e as VException
dim errNumber as Integer = e.ErrorNumber
dim errString as String = e.Message
MsgBox errString
end


Try
mReport.PrintToLocalPrinter("ZEBRA LP 2443", "paper=BarCode,copies=" + Str(PageCount) + ""
catch e as VException
dim errNumber as Integer = e.ErrorNumber
dim errString as String = e.Message
MsgBox " Report Print " + errString
end

What is the max length of the text you want to put into barcode?
QR code may fit more information in less space, but the scanner is much more complex.

Igor has made a few improvements that will help to fit the code into smaller space.

max 25 but i normal use like 15 or less

paper=BarCode

What will you get if you skip this printing parameter? Is it easy to check?

ok
i have to try that on customer site
thanks

Another thing to try is to set standard paper name.

From VStudio it is printed with the correct size, so what size do you set in the print dialog?

Here are possible values for paper parameter (in the first column, the second value is the corresponding constant in the Windows API):
{ "letter" , DMPAPER_LETTER },
{ "letter small" , DMPAPER_LETTERSMALL },
{ "tabloid" , DMPAPER_TABLOID },
{ "ledger" , DMPAPER_LEDGER },
{ "legal" , DMPAPER_LEGAL },
{ "statement" , DMPAPER_STATEMENT },
{ "executive" , DMPAPER_EXECUTIVE },
{ "a2" , DMPAPER_A2 },
{ "a3" , DMPAPER_A3 },
{ "a4" , DMPAPER_A4 },
{ "a4 extra" , DMPAPER_A4_EXTRA },
{ "a4 plus" , DMPAPER_A4_PLUS },
{ "a4 small" , DMPAPER_A4SMALL },
{ "a5" , DMPAPER_A5 },
{ "a6" , DMPAPER_A6 },
{ "b4" , DMPAPER_B4 },
{ "b4 (iso)" , DMPAPER_ISO_B4 },
{ "b4 (jis)" , DMPAPER_B4 },
{ "b5" , DMPAPER_B5 },
{ "b5 (jis)" , DMPAPER_B5 },
{ "folio" , DMPAPER_FOLIO },
{ "quarto" , DMPAPER_QUARTO },
{ "9 x 11" , DMPAPER_9X11 },
{ "9x11" , DMPAPER_9X11 },
{ "10 x 11" , DMPAPER_10X11 },
{ "10x11" , DMPAPER_10X11 },
{ "12 x 11" , DMPAPER_12X11 },
{ "12x11" , DMPAPER_12X11 },
{ "15 x 11" , DMPAPER_15X11 },
{ "15x11" , DMPAPER_15X11 },
{ "10 x 14" , DMPAPER_10X14 },
{ "10x14" , DMPAPER_10X14 },
{ "11 x 17" , DMPAPER_11X17 },
{ "11x17" , DMPAPER_11X17 },
{ "note" , DMPAPER_NOTE },
{ "envelope" , DMPAPER_ENV_ITALY },
{ "envelope monarch" , DMPAPER_ENV_MONARCH },
{ "monarch" , DMPAPER_ENV_MONARCH },
{ "envelope #9" , DMPAPER_ENV_9 },
{ "envelope #10" , DMPAPER_ENV_10 },
{ "envelope #11" , DMPAPER_ENV_11 },
{ "envelope #12" , DMPAPER_ENV_12 },

{ "envelope b6" , DMPAPER_ENV_B6 },
{ "envelope c5" , DMPAPER_ENV_C5 },
{ "envelope c3" , DMPAPER_ENV_C3 },
{ "envelope c4" , DMPAPER_ENV_C4 },
{ "envelope c6" , DMPAPER_ENV_C6 },
{ "envelope c65" , DMPAPER_ENV_C65 },
{ "envelope invite" , DMPAPER_ENV_INVITE },
{ "c" , DMPAPER_CSHEET },

{ "letter extra" , DMPAPER_LETTER_EXTRA },
{ "legal extra" , DMPAPER_LEGAL_EXTRA },
{ "tabloid extra" , DMPAPER_TABLOID_EXTRA }

I make a custom one with name BarCode

1) To fit 15 characters into Code 128 barcode, it is necessary to set the width to 50 millimetres.
Also note, the character set of Code 128 is limited to alphanumeric characters, any non-latin symbol will result in an error.

The smallest QR code fits into 11x11 millimetres square, but the scanner is more complex, I don't know if it is an option.

Maybe it is worth to use bigger labels? Or use shorter codes?

2) When you print from the Valentina Studio (and it is printed OK), what paper size do you set in the Print dialog?
