Android Question [Solved]Trouble printing

[RMarra]

I am trying to print a pdf using this code:

Dim prt As Printer
    prt.Initialize("")
    prt.PrintPdf( "SeatingChart", path, "SeatAssignments.pdf")

I have version 1.10 of the PRINTING library.

I get this error:

make sure to use a device with Android 4.4+

I have Android 9. Are there any additional libraries I need?

Are there any additional libraries I need?

they are here:Printing and Pdf creation

You need to jetify the library.

 

[RMarra]

When I run Jetifier, it says "All set. Nothing to do!"

 

[Erel]

Make sure that the library is in the additional libraries folder and NOT in the internal folder.

That was it! Thank you very much!
