Some printer manufacturers will provide special installation software on a floppy disk or CD-ROM and recommend using it for printer driver installation. These installation programs may fail to install a printer driver as they generally probe the hardware, such as parallel ports or USB ports. To install printer drivers under Win4Lin please use the method described in Printing in the Win4Lin Environmrent in the User's Guide.
If you do decide to print to a parallel port via direct port attachment as described in Direct printing in the User's Guide, please note the following caveats:
In Win4Lin 1.0 the driver that allows for direct parallel port attachment does not handle any interrupts and does not support DMA. This means that if the port is set to ECP mode in the CMOS/BIOS setup, printer and scanner drivers may try to take advantage of the Extended Capabilities of the parallel port. The result is malfunctioning software. Some drivers ignore the port setting of Windows95/98. Even if your parallel port is set to ECP mode with the Windows driver properties not showing any IRQ or DMA resources being utilized for that port, it is not a guarantee the printer manufacturer's drivers will not try to use a DMA channel anyway.
If you are experiencing problems with directly attached parallel ports, try to set your parallel port to SPP (standard) or bidirectional mode in your computer's CMOS/BIOS setup.
