LaserWriter 12/640 PS: How to suppress info page at startup?

That option is set semi-permanently inside the printer. You change it with "Apple Printer Utility", and you will need a Mac that can run Classic or OS9 to run the Utility, but only booting to a CD is required, you need not install OS 9 on a Hard drive.

One changed, the printer will remember the change permanently, so a friend or a local Apple reseller may be able to help you. If you have to take the printer somewhere, try not to shake up the cartridge too much or you will spill toner all over the inside of the cartridge and ruins its image quality.

The North American English version is available as the second and third links on the printing section of the Older Software Downloads page:

The links look like:

Macintosh/Printing/LaserWriter/Apple Printer_Utility_2.2Info.txt

As you know a MacBook can't run classic but you do have another option. If you have Windows on your MacBook or can get access to a Windows system you can use the Windows version to do the same thing. You will need to do a custom install for only the Apple Printer Utility as you don't need the other 2 things. You can get the program from http://download.info.apple.com/AppleSupport_Area/Apple_Software_Updates/English-North_American/DOS-Windows/Printing/ LaserWriter_for_Windows_NT/LWNT10.ZIP

Thanks for that link, Stuart!

I looked for the Windows version of the utility alone, but could not find it. I didn't know what Windows downloads it might be hidden in, and the knowledgebase does not appear to tell.

The OS9 program "Apple laserwriter utility" had an option for shutting off the startup page of all the apple laser printers. I used it to shut off the startup page on my laserwriter IIf.
