Accel Frontline — New HP laserjet printer not working

Sir/madam,
accel frontline worker has installed a hp laserjet printer at calicut bp last month . Now it is not functioning. When the power is switched on, the screen shows "hp" and it is getting stuck. I discussed this with your worker "nandha" who has installed this here ( iocl, chelari bottling plant, calicut). Please take immediate action as we are in immense need of it. Please fix this issue as early as possible
