Hi Vipin,

I can reproduce your problem. And these problems all exist in PB 12.6. It is normal behavior.

The issue also exists when you use the RDP method to connect to the machine, use a local machine, and even though when you don't use the Citrix machine.  

Please note that after the PB application is launched, it will get a default printer and store it to the application according to the current Windows printer settings.

However, after the PB application is launched, if you dynamically modify the default printer of Windows or highlight other printers, the settings won't apply to the PB app.

You can refer to the PB local help documentation for details and you can also check the online help in the link below:

PrintSetup

https://docs.appeon.com/pb2019r3/powerscript_reference/ch02s04s600.html 

Usage：

The user's settings have effect for the duration of the application only. After the application exits, printer settings revert to their previous values.

PrintSetupPrinter ()

https://docs.appeon.com/pb2019r3/powerscript_reference/ch02s04s601.html 

Usage：

You can display the printer setup dialog box for different printers by first calling the PrintSetPrinter function. You cannot change the printer by calling PrintSetupPrinter as you can with the PrintSetup function.

if you need to modify the default printer name stored in the application after the app is launched, you can use the PrintSetPrinter method to modify it.

See the sample code below:

long ll_place
string ls_setptr
string ls_prntrs = PrintGetPrinters ( )
 
ll_place=lastpos (ls_prntrs, "~n") 
ls_setptr = Mid (ls_prntrs, ll_place + 1)
PrintSetPrinter (ls_setptr)
PrintSetupPrinter ()

BTW, the printer setup dialog box window the PB Print method called is the Windows underlying window, so the default printer displays in this window is the same as that set in the current Windows system.

Regards,
