Print Timeout on electron 6

[budi7]

Hi,
i'm facing printing timeout error : [TimedOutError] Make sure your printer is connected.
Printer already connected (i can confirm that printer connection was not the problem, Printing to that printer can be done using this plugin demo app)

current environment:
Npm ver: 6.14.11
Node ver: 14.16.0
electron ver: 6.1.12
electron-pos-printer ver: 1.3.6

Tested on electron 7 and up, with no problem. The problem seems only occur in electron 6.x.x only.
Since upgrading electron to version 7 is not an option for my case, any suggestion or fixes will be very appreciated.

thank you
