troubleshooting definitely, and I do hope it is simple :-)
The station I'm testing with is a Thinknic with usb printers.
this is the lts.conf entry. (the printers where defined as /dev/usb/lp0
and lp1, /dev/usb is now empty.
changed devices to tty0 and tty1 to see if the queues will get created
correctly. now i can telnet into the ports 9100 and 9101 with the
connection staying on.
XSERVER = vesa
# PRINTER_0_DEVICE = /dev/usb/lp0
PRINTER_0_DEVICE = /dev/vc/0
PRINTER_0_TYPE = S
# PRINTER_1_DEVICE = /dev/usb/lp1
PRINTER_1_DEVICE = /dev/vc/1
PRINTER_1_TYPE = S
SCREEN_01 = startx
SCREEN_02 = shell
What are the devices for usb printers?
This is what the manual says:
"9.2.6. Printer configuration parameters
Upto three printers can be connected to a diskless workstation. A
combination of serial and parallel printers can be configured via the
following entries in the lts.conf file:
The device name of the first printer. Names such as /dev/lp0, /dev/ttyS0
or /dev/ttyS1 are allowed."
Fine as far as it goes, but what happened to /dev/usb/lp(x) devices?
thank you, julius
