My LaserJet IIP Plus, which I use with a Jet Page PostScript Cartridge, is not printing. It prints nothing at all! The printer displays a "ERROR 34 Flushing", which I can�t find on the manual. Problems started when I changed my computer for a new one and, at the same time, decided to send the printer to change the rollers and do some cleaning. Before that it printed everything perfectly. Now:
When the printer is with the cartridge, it prints the PRINTER Font Test and Self Test correctly. But when I send, for instance, a Word page, then comes the ERROR: 34. It prints nothing whatsoever.
When I use the printer without the cartridge, it prints the PRINTER Self Test correctly. When a send a text from a software, it prints with slight errors (some letters are not perfectly aligned). Anyway, I want to use the printer with the cartidge.
I've already tried different printer drivers, cables and so on � unsuccessfully.
I've been doing a lot of research for some time. I've tried HP, IBM, Apple, Google, etc. So, while I was doing those researchs I found this:
"Adobe, Nothing Prints or Error: 'Flushing' When Printing to IBM 4079 PostScript Printer. Issue When you print to an IBM Lexmark 4079 ...
pagemakersupport.adobe.com/adobeknowbase/ root/public/pm2476.htm?DREID=6727"
Seems exactly like my problem. Problem is the page is not available. That's how I came to the Adobe site. I went first to the Pagemaker Forum and now here I am�
Does anyone know what kind of error is this and what should I do to get my printer printing again?
Thank you all very much
