Ignore my previous message. I figured out how to print from XyWrite in vDosPlus on the Mac - it worked by loading a PCL driver and then using my PDFToPrinter.exe to work with the output from LPT1. And, unless I’m completely wrong, the line I need in STARTUP.INT is BX LOAD C:\XY4\HPLJ-4.PRNQ2 ;*; with the BX and Q2 inserted with the PFUNC command. I’ll be posting a link to a working, printing XyWrite-on-the-Mac setup before long. I would really prefer this to use a 35- or 43-line window, and will once again be grateful for anyone who can help set this up. Many people provided helpful suggestions when I asked about this in the past, but I couldn’t make any of them work correctly. Stay tuned.
