Last month, the company said that brokerage D Roseman had requested the immediate repayment of a €2m (£1.8m) loan, which this morning confirmed is due to be recovered at the end of the month.
This, in effect, gives the company two weeks to secure additional funding to repay the loan, which it has previously stated would force it to "consider its position as a going concern".
In a statement to the London stock exchange, where NDPS is listing on the AIM market, the company said that the board "continued to negotiate for long-term solutions" with its key shareholders Polar and Creacorp.
However, it added that it would "need to consider a CVA for the company, in order to try and come to a settlement among all creditors", if no sustainable solution could be reached.
Under a CVA, a company comes to a legally binding agreement in which it agrees to pay all or, more commonly, part of a debt off in structured payments while it continues to trade.
It has been a difficult 12 months for NDPS, which last October put its French manufacturing arm into the French equivalent of administration. Nipson SAS exited Redressment Judiciare in July.
NDPS is the parent company of Nipson UK and manufactures the Varypress range of digital presses.
Nipson UK managing director David Mooney has previously said that the profitable UK part of the business was unaffected by the negotiations.
