I currently have my GS attached to a large college appletalk network. My
configuration is as follows:
1 Meg
GSOS 5.0
Farallon Phonenet connector
On the network, I have had no problems accessing mac servers or using the
LaserWriter Cdev to choose a printer. My problem arises when I attempt to
print. When I try to print, The print manager returns error $1306. My actual
port has been test (GOOD) by printing with mac, and my version of GSOS has
printed from another location on campus.
Does anyone have any idea of why I cannot print??
One aside, I have actually print on 3 separate occasions...Thesee were times
corresponding to relatively low network usage. My opinion seems to lead to a
timming out of some sort, because of network load. Has anyone else encountered
such a problem--If so does anyone have a fix...or could point me into the right
code to look at...
Basically any help would be appreciated
Thanks

As printers evolve, better designs are worked in. One annoyance of the "classic" LaserWriters is that when they take the sheet out of the tray and push it through the printer and under the printing mechanism (or over it, whatever), they lock out interrupts (what AppleTalk is based on) for a period of *six seconds*. This isn't long to you and me, but it's forever to an interrupt handler and to AppleTalk. The papOpen routines in the IIgs don't try for more than about 2.5 to 3 seconds to connect to the printer, and if they can't connect, the Print Manager will return error $1306 ("Connection can not be established with the LaserWriter"). This is more likely to happen when other people are printing, since the critical time is when the paper's moving through the printer. Unfortunately, some applications treat each page as a separate document, requiring a new connection to be opened with the printer while the previous page is being printed. This often fails. We have not seen this happen with a LaserWriter II. I hope this helps somewhat. -- ----------------------------------------------------------------------------- Matt Deatherage, Apple Computer, Inc. | "The opinions expressed in this tome Send PERSONAL mail ONLY (please) to: | should not be construed to imply that Amer.
