HP LaserJet 4 Plus: error W2 Invalid Pers

Im running mac os 10.3.4 and trying to print with an HP LaserJet 4 Plus via appletalk...I can communicate with the printer through a jetdirect 300x, but when i try to print something, the printer's interface immediately gives me error W2 Invalid Pers.
I've done a little research on the error, but i can't find a way to fix it.

Any suggestions?

Did you ever get a reply on this? I'm having the same problem hooking up an HP 4Plus onto a powermac running panther

If your Laserjet 4 Plus doesn't have the Postscript module installed, you will see this error msg.

If you need the postscript simm and the 4 extra mbs to run it, email [email protected] He has some in stock.

Instead of answering this often asked question, I'm going to suggest you type your query into the site search engine and then you can read the responses and you can figure it out for yourself.

Dear Anonymous
Not being a guru I was frustrated by downloading a driver from the MicroSoft site that didn't work and gave the error message discussed here. Your mail suggestion and link worked a treat and saved me prodigious amounts of heartburn. I'm very, very thankful to you Mate.

The Laserjet 4 driver at your suggested site http://h20000.www2.hp.com fixed my printing driver problem perfectly....THANKS! - unknown
Will this work with an iMac as well?

Thanks, I'm going crazy trying to get it to print.

Mac OS X users: simply install and use the Gutenprint driver for your printer. Download it here:

When I got this message installing Ubuntu 7.10 , I reinstalled the printer (in my net 192,160.40.200 this is not important) as a :


PCL 4 Printer

Generic PCL 4 Printer Foomatic/laserjet


No more "W2 Invalid Pers" or "Overflow" message !!

Not on a MAC. You need the postscript simm along with i believe an extra 4 more meg of ram for the 4 plus to work on a MAC. Contact [email protected] as I am sure he has what you need in stock and a reasonable cost.
