Excel for OS/2: IOPL Required with Epson Driver PSS ID Number: Q50723 Article last modified on 06-23-1993 PSS database name: W_eXceL

OS/2

Summary:

The Epson printer driver shipped with Excel for OS/2 requires I/O privilege. To grant this privilege, it is necessary to set the line

IOPL=YES

in the CONFIG.SYS file. Without this modification, the alerts “Not Enough Memory” and “Cannot Open Printer Driver” are displayed whenever the driver is accessed.

When trying to install the Epson driver from the Control Panel, you may get the following message:

PMV2008: Cannot find any printer files in this directory. Type the full path of the directory that contains your printer files.

The symptom is different but the cause is the same. Add the above statement to your CONFIG.SYS file.
