Does DWP pay for the printing cost???

Hi, not sure where to post this quesitons as it could be eaely under several forums. DWP has asked me to send some additional information. For some silly reasoon thay do not do emails so I need to send by post. I neededd to go to town to the local library and print documents (i took a taxi) and paid the printing there. Yes the envelope is provided but how do they expect me to get printed documents they are asking for. Should I enclose the printing and taxi receipts and would DWPpay for these. Thank you
