Re: increase number of printers?

I also would like for this to work. We are in the exact same boat with
some actively developed software that uses Windows add-on. I gave
written a script that extracts the fax no. from the print job and
faxes the invoice, but it requires to change the printer. LPT1-LPT3
are used as sales printer, label printer, warehouse printer. If dosemu
supports LPT4+ this process would be much simpler.
