I have issues with samsung m2070 printer. Whenever I try to print certain documents like tickets or pictures of documents it's freezing and keeps saying "printing..". At first I couldn't realise that it's only for certain documents so I even bought new printer (same model) and issue persists.
Printer is connected to one pc and then shared across several (same issue with all of them) I have an idea that its because of complex files so played around with several functions like eco printing and etc. Even tried changing image to grayscale and but its the same.
It used to be alright.
P.S. Some times when printing PDFs with text only generated from html same thing happens but rarely.
