Can print direct but not thru lpr spooler?
Red Hat 7.2 (2.4.7-10)
I've only been able to get printers working on the parallel port. I need especially to get a serial printer working. The printer and serial port seem to be OK since I can print directly to the printer via: 'date > /dev/ttyS1' and 'date | lpr -Y -P/dev/ttyS1'. But although the printer looks correctly setup in printconf-gui, and /etc/printcap looks OK, when I do 'date | lpr -Y -Pprintername' - nothing!
Can anyone point me where to go from here?
