Is it permissible to return to a job that conflicts with Friday and congregational prayers, knowing that it provides for the household's needs without recourse to government assistance?

Working in the printing of forbidden materials is not permissible. As for permissible work, it is allowed on condition that one does not miss the Friday prayer unless there is a valid excuse, such as illness or travel, or if leaving the work would lead to an unavoidable harm to one's livelihood. One should also strive to perform congregational prayers even at the workplace, and seek permissible work that does not prevent one from performing the Friday prayer and congregational prayers.
