#43 Dot-matrix printer emulation

[Frederic Weymann]

This patch adds the emulation of a full-fledged
black/white 48-dot matrix printer supporting ESC/P and
ESC/P2 to DOSBOX.

ESC/P(2) were the quasi-standards for matrix printers,
so the printer is able to emulate most 24/48-dot printers
from EPSON and other manufacturers.

The printer offers different paper sizes, resolutions and
output methods which can be selected in the DOSBOX
config file.

The Freetype2 (www.freetype.org) library and TrueType
fonts (GPL'ed ones included in the patch) are required to
render characters.

Besides the actual printer emulation, this patch adds a
few features to existing code in order to enable
programs to actually contact the printer:

• BIOS "printer" interrupt 17

• LPTn DOS device

• Support for getting a device handler by creating it
  (DOS_CreateFile)

• Dummy versions of the DOS-IOCTL functions 0x01 and
  0x0A (dos_ioctl.cpp)

• DOS function "Write Character to PRINTER" (0x05)

The fonts are too big to be attached here, so I posted them
in the forum:

I added a few extra features:

• Output of created pages as postscript

• Multipage support (more than one page per
  postscript/printer job)

• Alt-F8 no longer "ejects" a page that is blank

I couldn't compile with your patch.
There was a compile error.

The same result with floams's.

I updated the virtual printer patch to make it compilable with the latest sources. I did not change any of the internal logic. I'll make it available soon.
