Printer is HP LaserJet 5L on lpt0 (on-board port). Custom SMP kernel Parallel port section of kernel config: # ppc ISA-bus parallel port interfaces. # device ppc0 at isa? port? net irq 7 controller ppbus0 controller vpo0 at ppbus? device nlpt0 at ppbus? device plip0 at ppbus? section of dmesg output: ppc0 at 0x378 irq 7 on isa ppc0: Generic chipset (NIBBLE-only) in COMPATIBLE mode ppb0: IEEE1284 device found /NIBBLE Probing for PnP devices on ppbus0: ppbus0: <Hewlett-Packard HP LaserJet 5L/0101.03> HP ENHANCED PCL5,PJL nlpt0: <generic printer> on ppbus 0 nlpt0: Interrupt-driven port plip0: <PLIP network interface> on ppbus 0 >Description: Using the ppc controller and nlpt0, I was unable to produce useful graphic printed output. All suitable drivers at all print densities produced memory overruns in the printer. (partial graphic output folloed by lines of garbage characters). >How-To-Repeat: Using apsfilter port, set up Laserjet printer using any of 'laserjet', 'ljet4', 'ljet4dith' drivers. Specify any print density (most default to 600dpi, problem is observed at 150dpi and up). Print test page through apsfilter setup, observe bad output. >Fix: Removing ppc0 and associated entries and restoring (deprecated) lpt0 solved the problem. printing successful at 600dpi. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
