The printer is a HP 2100M. I tried using extended mode to fix another problem where the printer occasionally hangs necessitating a reboot after a suggestion in PR 14787 (no PR submitted for the original problem as I want to investigate a bit further) dmesh output: ppc0: <Parallel port> at port 0x378-0x37f irq 7 flags 0x40 on isa0 ppc0: SMC-like chipset (ECP/EPP/PS2/NIBBLE) in COMPATIBLE mode ppc0: FIFO with 16/16/8 bytes threshold ppbus0: IEEE1284 device found /NIBBLE/ECP Probing for PnP devices on ppbus0: ppbus0: <Hewlett-Packard HP LaserJet 2100 Series> PJL,MLC,PCL,PCLXL,POSTSCRIPT lpt0: <Printer> on ppbus0 lpt0: Interrupt-driven port >How-To-Repeat: # lptcontrol -e # lpr -Plp somefile.ps >Fix: None known >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
