Hi,

I can't print on a custom printer from PDFViewerSDK (last release).

I've this problem since December 2015 but no upgrade had solved that.

This is sample code I use:

****

Dim my_printer As String = AxDPVActiveX1.DQPLNewCustomPrinter(stampantePredefinita)

iPrintOptions = AxDPVActiveX1.DQPLPrintOptions(1, 1, System.IO.

Path.GetFileName(filePDF))

AxDPVActiveX1.DQPLPrintDocument(my_printer, PrintDialog1.PrinterSettings.FromPage, PrintDialog1.PrinterSettings.ToPage, iPrintOptions)

****

I've no errors but I can't print.

If I use

AxDPVActiveX1.DQPLGetDefaultPrinterName()

Print correctly.

There is a bug in DQPLNewCustomPrinter ?

Can you help me?

Thanks,

regards.

Hi Marco,

what's inside stampantePredefinita?

It have to be the correct system name of an installed printer.

If there's one character wrong it won't work.

Use the GetPrinterNames to get the correct names/description of the installed printers.

Another point where a prob can be is the used string format: It's unicode.

If your prog.language handle strings as strings and not unicode strings then there can be the prob, too.

Hi Ingo,

in VB.NET, it's my debug:

*****

?stampantePredefinita

"\\pc-bernardoni\HP LaserJet 1022"

?AxDPVActiveX1 .DQPLGetPrinterNames

""PDFCreator","infotec MP 171","Fax","Epson Studi","\\battini-pc\Kyocera FS-1300D KX","\\pc-bernardoni\HP LaserJet 1022","\\pc-lami\HP LaserJet 4 Plus""

?my_printer

"QPLPrinter5763CF00"

******

Then the method:

AxDPVActiveX1.DQPLPrintDocument(my_printer, PrintDialog1.PrinterSettings.FromPage, PrintDialog1.PrinterSettings.ToPage, iPrintOptions)

don't works

Hi Marco,

i've done a lot of individual development regarding PDF printing with QuickPDF and it works like a charm ... always ;-)

The probs can be the doubled backslash from the net-directory - that's not a real printername!

If you're going on your printerpage... what's the name under the printer icons?

Try one without the doubled backslash - i think it will work.

Rename the one with doubled backslash into normal name - does it work?

No, if I rename the one with doubled backslash doesn't work.

Ifcact, at debug before rename I've this:

?my_printer

"QPLPrinter4F8856FD"

After the change name, I've this:

?my_printer

And don't work.

If you want, you can also connect on my PC to verify the bug in the libraries.

Thanks,

regards.

Hi Marco,

this is a user-user-forum here.

Users are helping each other.

I'm doing this in my free time - so why should i connect to your pc?

For real bugs in the library there's an official page from debenu.

Thanks a lot Ingo.

The problem is that I have reported this bug in Dicember 2015 and I have not had the solution.

And this is a real problem for me...

Regards.

Hi Marco,

Please check out this thread. Could be a help for you?

http://www.quickpdf.org/forum/getprintername-question_topic1623.html

BTW: What's your developement ide?

"Dim my_printer As String" looks like VB? ...VB6?

You've read that the function needs a unicode string?

http://www.debenu.com/docs/pdf_library_reference/NewCustomPrinter.php

Perhaps this is the reason for the issue?

I've sent an email directly to the publishers of the library regarding your issue...
