Anyone encountered problems with the DeskWriter 2.1 driver (the newest) and Sys 7 virtual memory? When printing from most applications, especially Word and sometimes PageMaker 4, the printer just stops after a while, saying something like "DTR buffer overflow". Usually happens after 1/3 of a page or so. Once VM is off, things work fine. System: SE/30 5M 40M internal SyQuest cartridge drive non-AppleTalk Deskwriter 8 megs virtual memory -dave.

The driver won't work with VM on. The HP people say they are working on it, but they seem to be not quite sure if the problem is with System 7 or the driver. So, an upgrade/fix is uncertain. However, it seems to work fine if you turn BOTH VM and 32-bit addressing ON. I haven't done extensive testing on that but I've printed something with no trouble at all. Good luck! -Ki Wong 6500wong@ucsbuxa.

>Anyone encountered problems with the DeskWriter 2.1 driver >(the newest) and Sys 7 virtual memory? The DeskWriter uses DTR handshaking at 57.6Kbaud and unfortunately the Macintosh does not reliably handshake at 57.6Kbaud under virtual memory. Until this is fixed or a workaround is done to the DeskWriter driver, turn off virtual memory. Steven Miller Vancouver Division Hewlett Packard

I forgot to mention that AppleTalk works just fine with Virtual Memory under system 7.0 with the DeskWriter. Until this problem is resolved, this will allow you to use VM with the DW under 7.0. Also, turning on 32-bit appears to make serial handshaking more reliable, although I don't know if it fixes the problem or just makes it much less frequent. The problem with 32-bit mode is that not all applications support it and only about half of the machines that can run VM can also run in 32-bit "clean" mode.

What do I need to connect my SE/30 to my DW via Appletalk? I won't have
anything else hooked up to either one, I just want to be able to use VM. Isn't
Appletalk going to cause my printer to print slower? And finally is this
a very expensive solution to the VM problem?Charlie.Mingo@p4218.f421.n109.z1.FidoNet.Org (Charlie Mingo) (06/13/91)

I have one of the original DW's, from before they had AppleTalk.
Is there any way to get an upgrade? (Useful both for this and for
Freedom of the Press.)
