Hi Oleg
How are you?
So.. We are having a problem when printing QR Code by Fomin... Sometimes in some
RPT, the QR Code are not printed.. just a white space are printed in QR Code
place.. if the user try again to print the report, works, but sometimes didnt
work.. just after 3 or 4 attempts the QR Code are displayed and printed.. This
report are printed direct to print (not previewed before).
How to solve this randomic error?
We use Clarion 6.3 and Fomim 3.36
Thank you

Nobody reported such a problem yet. Is there any chance I can reproduce and
investigate the issue?

Hi Oleg.
Thank you for reply.. Itīs very randomical.. Here in our lab, itīs never
happened.. And in our customers, in 98% its work perfect.. but 1 or 2 invoices
in a day, it was printed without QrCode.. and if the user print again teh same
invoice, print correctly..
We already try to change the size of QrCode, change the localization of QrCode
in invoice.. but without sucess..
The QrCode have just the invoiceīs number.. and this number (without QrCode) is
printed in another frame correctly.
We try to change some fields of QrCode configuration in Fomim, but without
sucess too..
Could be some QR Code parametrization?
We try to change some configurations os qrcodeīs frame, but without sucess too..

The question is what is the common denominator? Does it happen on a single
workstation? In this case it looks like environmental issue, asking for %temp%
folder cleanup, memory and/or disk diagnostics, other system maintenance actions
up to hardware change or reinstall Windows and software.

Hi Oleg,
In our production environment, weve encountered an issue where the QR code is
not printed in certain reports.
To reproduce the problem, we simulate the scenario by repeatedly calling the
print fomin report command a large number of times. For example, invoking the
print fomin report command 2000 times and sending the print jobs to the
Microsoft Print to PDF printer. Under these conditions, some of the generated
PDF reports intermittently fail to display the QR code.
Could you please advise on possible solutions or workarounds to overcome this
issue?
Thank you,
Regards,
Nelson

Just wondering how you managed to print report automatically to Microsoft Print
to PDF printer. Mine is always asking for output file name to save.
Can this be reproduced with FRB example app or with your application only?

Hi Oleg,
Sorry for the late reply. I realized there was a mistake in my previous message.
To enable automatic printing, we need to use PDFCreator. Please ensure it is set
to automatic mode, with the target directory defined, and the filename
configured to append the <Counter> value. This way, PDFCreator will process the
print job without prompting for a filename.
You may note that some of the reports are generated without a QR code. In my
production environment, Im using PDFCreator to automatically create PDF
outputs, and this setup has been working smoothly.
Regards,
Nelson
