9534.0. "Garbaged print-out on Alphaserver 4100/300" by MANM01::JUNHERNANDEZ () Thu Apr 17 1997 07:48

    Has anybody encountered garbled print-out on a printer connected to the
    parallel port of the Alphaserver 4100/300. I've tried replacing the
    printer cable and also the printer, but the problem is still there.
    I also replaced the RIO module and the EISA/PCI module, but the problem
    still remains. The command is used to test the parallel port is "cat
    /etc/profile > /dev/lp0". However, when I tried  connecting a HP
    DESKJET printer to the Alphaserver 4100, the problem was gone. The
    previous printers I was using is Epson LQ2170 and Epson LQ1170. Both of
    these printers are dot matrix printers and these units are working fine
    when connected to Alphaserver 400.I've also tried upgrading the
    firmware using Firmware CD 3.8. Is there a known problem with dot
    matrix printers ?
    
    Thanks

    Hi, 
    
    	I've seen that the /etc/profile > /dev/lp0 corrupts output on a 
    Declaser 2100 (text, not postscript) on a 4100.
    
    	The Declaser 2100 works perfectly on netque box / PCs / alphastation.
    The symptoms was that only 1 character of 2 was print : ie
    
    	# cat file 
    	123456789
    
    	output on the declaser :
    	1357
    
      strange isn't it ...
    
    Manuel.

I don't recommend using any cable over 10ft. Although rare, some hardware will
have problems using cables over 6ft.
