Hi infos,
Could you provide a little more information to your question as you mention a Windev Mobile application and then a PC printer.
What is the requirement?
What printer are you trying to print to?
What are you trying to print?
What connection do you have between the printer and the device, eg Bluetooth, WiFi, LAN?
What mobile OS are you using?
If you can provide more information I may be able to offer some assistance.
Kindest Regards,
Lee
