Find a parallel port mode.
The default value should be SPP.
Just change it to ECP
In addition, after changing this port mode,
Maybe the printer needs to be reinstalled when going east.
I suggest you delete the printer and reinstall the driver.
Parallel protection mode
Sets the value that can be set for the transmission mode of the parallel terminal: SPP (standard parallel port. Normal mode) represents the standard oil well pipeline port mode. This is the default setting; ECP (Extended Parallel Port) stands for Extended Parallel Port Mode; EEP (enhanced parallel port) means enhanced parallel port calibration, and ECP/EEP means enabling both ECP and EEP modes.
Among them, ECP mode is mainly applied to a new generation of printers or scanners. This mode supports RLE (Run-length Coding) data compression and DMA direct memory reading, and the highest transmission speed can reach 4 MB/s..EEP mode is mainly used for non-printer parallel peripherals, such as external drives, hard disk and network card, and the highest transmission speed can reach 2 MB/s. Optimization suggestions. This option can be set to ECP/EEP, so that no matter what mode the device supports, the BIOS can correctly identify the resources related to well allocation.
