SUMMARY

A "Device Unavailable" or "Device I/O" error will be generated when attempting to print with LCOPY, LLIST, LPRINT, or "LPT1:DIRECT" (character mode output) to an Apple ImageWriter I, II, or LQ over the AppleTalk network. LCOPY, LLIST, LPRINT, or "LPT1:DIRECT" requires a directly connected ImageWriter I or ImageWriter II. These statements are not supported on the ImageWriter LQ (which is a graphics-mode printer) or on a LaserWriter.

To output to an ImageWriter I, II, or LQ over the AppleTalk network, you must OPEN the "LPT1:" or "LPT1:PROMPT" device name as device #n and send output with the PRINT#n, WRITE#n, or WINDOW OUTPUT#n statement. You must also have the "AppleTalk ImageWriter" file (or "ImageWriter LQ" driver for the LQ) installed in the System folder and selected in the Chooser to print over the AppleTalk network to an ImageWriter.
