Laserjet 3150 doesn't print

HP Laserjet 3150 connected to parallel port doesn't print test page (or anything). The printer is detected and installs fine. It says it printed fine but nothing happens and no errors. Initially I got Device communication error 5012 hplip... but now the error is gone after installing the latest hplip and enabling EPP in bios. Prints fine on winXP. Tried using the repository drivers, followed by compiling the latest from HP. Also tried the hpijs driver. Tried rebooting. Tried adding via system printer dialogue and hp-setup. Network printing to another printer works fine(HP Officejet L7555). Verified the bios is using EPP mode. Verified the kernel sees the /dev/parport0. Verified the following:
lsmod | grep lp
lp 17759 0
parport 46345 3 lp,ppdev,parport_pc

dmesg | grep par

I read another post about the wrong command set for this printer but I don't know where to change it or what to change it to?
