I'm assuming you are the UK sponsor?
Printed electronic payslips are not acceptable on their own. They must also be accompanied by a letter from HR confirming their authenticity.
Alternatively, you could see if HR will print official copies of the payslips for you.
From Appendix FM-SE:
(bb) Payslips must be:
(i) original formal payslips issued by the employer and showing the employer’s name; or
(ii) accompanied by a letter from the employer, on the employer’s headed paper and signed by a senior official, confirming the payslips are authentic;
