            Bug ID: 39056
           Summary: Redirect a device printer port to a print command
                    (lpr)
           Product: Wine
           Version: 1.7.48
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: spooler
          Assignee: wine-bugs at winehq.org

Sometimes I need to write directly to a print port.
That's because I have a old program that works only with ports named lpt[1-4]
or com[1-4]

I can do it creating a link to my device to the dosdevices folder.
E.g:
ln -s /dev/lp0 ~/wine/dosdevices/lpt1
ln -s /dev/ttyUSB0 ~/.wine/dosdevices/lpt2

Typing commands like echo 'hello' > lpt1 will work great.

There are some cases that my printer is not directly connected to my computer.
By example my Brother DCP-8085DN printer that works over network, a wireless
printer, or same my epson lx300 using lpt1 port but instead is installed on
another computer.
To map this kind of printers I use cups and it work on wine using print dialog
(e.g printing using notepad).
But what about if I need to use my old dos program or would like play around
with wine start.exe program and type commands like echo 'hello' > lpt1
Wine start.exe returns File not found.

Cups doesn't create /dev/xxx devices to printers. So I can't do a link to
dosdevices folder and I have to use the lpr command to print.
One solution is create a file named lpt1 on dosdevices folder and use loop
script in linux cheking for changes and redirect data to lpr.
I can do it easly using the following procedure:
cd ~/.wine/dosdevices
mkfifo lpt1
chmod 666 lpt1

And create a running forever script like:

while true
do
cat ~/.wine/dosdevices/lpt1 | lpr -o raw -P cups_printer_name
done

While this method can work would be great if we could do it only using wine
ways and therefore no need to such script.
