USBPRINT in Win3.11

[Serg]

Hi.
I use printer HP LJ P1505n. Your program USBPRINT.COM well works under MS DOS 6.22, the printer prints (not so fast). Whether works USBPRINT.COM in Windows environment 3.11. I tried, but USBPRINT.COM does not see the printer.

I use printer HP LJ P1505n. Your program USBPRINT.COM well works under MS DOS 6.22, the printer prints (not so fast).

It probably won't be very fast until there is a USB 2.0 (EHCI) host driver developed. My emphasis so far has been on reliability and compatibility, rather than speed.

Whether works USBPRINT.COM in Windows environment 3.11. I tried, but USBPRINT.COM does not see the printer.

It's been a long time since I've used Windows 3.x, but I think I remember there being ports called LPT1 & LPT1.DOS, LPT2 & LPT2.DOS, etc. If you have LPTx (without the .DOS at the end selected (which you probably do), USBPRINT won't work. USBPRINT emulates the printer at the BIOS level, not the hardware level. Try selecting the LPTx.DOS port in Windows instead of LPTx -- I think that might fix your problem.

In general, if a program gives you an option of printing to the hardware (an I/O port number like 278h), using the BIOS (INT 17h), or using DOS (INT 21h), do NOT use the hardware option -- use either the BIOS or DOS option.
