[comp.sys.mac] How to set the Laserwriter timeout?

ELLIE@merrimack.edu (12/15/89)

I have a Laserwriter connected to an IBM compatible running WordPerfect 5.0.
When I send a file to the printer, pages with straight text come out (usually),
but pages with tables don't print at all.  The orange light on the printer
blinks continuously for several minutes, but the page never prints. 

I called WordPerfect Support and they said that the timeout in the printer
needed to be changed to infinity.  I don't know how to do this.  

Any suggestions?  I have a copy of SendPs. 

Can the Postscript command to change the timeout also be sent from the MS-DOS
machine?
