Downloaded h-a-l's mega Build SE and also Port Talk driver. I'm trying to send print output from a program that allows me to specify the LPT1 port. Virtual Printer option works fine but for reasons I won't bore you with, I'd like to try the parallel port passthrough too, using Printfil to capture the LPT1 port. I'm on WinXP.

I'm assuming I've got the port talk driver installed correctly as status window says:
"The port at 0x378 was detected as ECP port."

Here's the relevant section from my dosbox.conf - maybe I've got it set up wrong?? Because this build has merged LPT and Virtual Printer I'm not sure how I should set it up......

[printer]
# printer -- Enable printer emulation.
# dpi -- Resolution of printer (default 360).
# width -- Width of paper in 1/10 inch (default 85 = 8.5'').
# height -- Height of paper in 1/10 inch (default 110 = 11.0'').
# printoutput -- Output method for finished pages:
# timeout -- (in milliseconds) if nonzero the time the page will
# be ejected automatically after when no more data
# arrives at the printer.
# png : Creates PNG images (default)
# ps : Creates Postscript
# bmp : Creates BMP images (very huge files, not recommend)
# printer : Send to an actual printer (Print dialog will appear)
# multipage -- Adds all pages to one Postscript file or printer job until CTRL-F2 is pressed.
# docpath -- The path where the output files are stored

printer=false
dpi=360
width=85
height=110
printoutput=png
multipage=false
docpath=.
timeout=0

[parallel]
# parallel1-3 -- set type of device connected to lpt port.
# Can be:
# reallpt (direct parallel port passthrough using Porttalk),
# printer (virtual dot-matrix printer, see [printer] section)
# Additional parameters must be in the same line in the form of
# parameter:value.
# for reallpt: realbase (the base address of your real parallel port).
# Standard ports are 378, 278 and 3BC. The first two can be ECP ports.
# PCI add-on cards may use nonstandard ports, look them up in the device manager.
# Default: 378
# You have to install the PortTalk driver from
# http://www.beyondlogic.org/porttalk/porttalk.htm first.

parallel1=reallpt realport:378
parallel2=disabled
parallel3=disabled
