Hi and welcome to FixYa!

Well if that's the case, the printer should be detached or powered of during call operations. The printer detects incoming calls that's why it triggers it to operate. Turning it off during operation will surely be the solution.

Hope this helps and thank you for using FixYa! Have a good one!

voice not hearable on incoming calls and outgoing calls

Turn up the volumes on Ear piece -during- a call (on the side of the phone <===>) and on the speaker at any time. The joy stick does it I think.

Have the audio jack repaired it's not making contact on the connecting plates properly. You ould have a go at this if you are very good with fine electronics
