I have connected an old parallel printer to my QNX 6.3 configuration. When
I try to print something “ls > /dev/par1”. The printer is triggered and
gives the impression of printing the directory, only the paper remains
blank. The printer works fine attached to my Windows laptop, so the ink
cartridge is OK. The printer is a OKI Microline 521, any ideas??? Do I
need to configure QNX?
