Printer Not Activated -30 Time Limit

[dempsey]

I've read topics that state the Enable Printer call "expires" after a period of time and printer usage returns "Printer not activated error -30".

I understand the reason for this behavior.

How long will the printer remain enabled? What's the timeout value (so that I can ensure it's never a problem for my application)?

Hello,

The printer will remain active for 20 seconds.

You need to call EnablePrinter() right before printing or when catching the EnablePre() event fired by the driver.

How can I do this? where and how?

[Joan]

You can do this if you are using the PDF Converter from inside your application programatically.
I.e if you are using the Developer version of the PDF Converter.
This version can't be used directly from any Windows application, it should be used programatically from inside your application.

If you are using the End User version of the PDF Converter EnablePrinter() doesn't apply.

Does anyone know of a way you can extend the 20 seconds the printer is enabled for? Is this property of 'EnablePrinter' configurable?

Hello,

Unfortunately there is no way to extract the 20 seconds the printer is enabled for. This function is not configurable.

To get a timeout of more than 20 seconds you need to contact support@amyuni.com and request a special activation code while stating why you need more than 20 seconds activation time.

As long as enabling the printer more than once in the code doesn't drastically effect memory it shouldn't be a problem. Thanks!

Hello,

Enabling the printer more than once in the progam doesn't have any side effects and it is required.

You need actually to enable the printer right before each printout or when catching the EnablePre() event.
