Under some circumstances you do not get significant inflation. Quantitive easing was just printing money. The money you got as a mortgage to buy your house did not exist until the bank/building society wrote a cheque. Of course at times it goes very badly wrong - hence 2008.
I found Yanis Varoufakis' book "Talking to my daughter about the economy" interesting - he thinks about printing money this way as borrowing from the future, rather than borrowing from another source. Thinking about that mortgage - we create the money by working/being paid/paying it back - in the future in other words.
