Details

• NEWPRINT/Multi is a Wi-Fi-enabled "virtual" printer adapter that connects to your computer's printer port and your local Wi-Fi network to send printer output to any device that supports a modern browser (iPad, Desktop PC, Mac, etc.).
• The NEWPRINT web interface can show printer output as plain text, hexadecimal values, Print Shop graphics (Apple II), or Apple IIgs GS/OS graphics printing.
• Text mode output does not (currently) understand special printer control codes used by most word processors (BOLD, multiple font sizes, Form Feed, etc.).
• The NEWPRINT web interface is available from any browser on your local Wi-Fi network at newprint.local
• NEWPRINT uses the standard HTML WebSocket API so you can even write your own web-based or desktop interface for displaying and processing NEWPRINT output.

Note: A power adapter (+5v DC) and printed User's Manual are not included to keep prices low. See the PDF User's Manual below for more information.

Apple II Printer Card Notes

• Some Grappler printer cards are missing pin #2. This is intentional and was designed to prevent you from connecting your ribbon cable backwards. This is fine as NEWPRINT does not require pin #2.
• If you have an older NEWPRINT card please contact me for a fix.

Apple IIgs Notes

• Some IIgs models may require a "newer" Grappler+ card (with 74LS374 in U10). The "old" Grappler+ card (with 74LS373 in U10) may have timing issues on the GS.
• My setup is a ROM01 IIgs with the older (373) Grappler+ card and I have no issues
• See this link for Apple's Tech Note on this issue
• If you are using one of the older Grappler+ cards (373 chip), set dip switch 1 to OFF
• If you are using one of the newer Grappler+ cards (374 chip), set dip switch 1 to ON

Apple II Series Cable Installation

• See the PDF User's Manual below for a few pictures and tips on how to install the ribbon cable through the rear slots without damaging your cable
