I managed to compile DosBox MB6 with some help on my Ubuntu 12.04 system. And although everything seems to work well, there is no way to get it to print "dir *.* >prn" from anywhere else than the C:\ root directory.
I have compiled it twice, once with the original files that have the update "parport_2nd_attempt" included, and a second time in order to be sure it was not the update that was at fault, without the update, using the original files only.
Both versions show the same problems.
I can get a directory listing of sub-directories by typing: "dir > c:\prn", but Dos programs such as dBase 5 will not print and come up with an "invalid printer port" error.
I have tried different approaches for the "parallel1=" setting in dosbox-mb6.conf and although a number of these work they again will only allow one to print a "dir *.* >prn" from the root directory on the C:\ drive.
It appears there is some bug in the source code of DosBox-MB6 for Linux.
Can anyone help with a solution? Thanks, Paul.
