My LJ2 doesn't have much memory...

I've finally repaired an HP LJ Series 2 after 6 months of cannibalizing two other LJ's for parts.  (yes, I'm a starving student) It prints ASCII nicley, but sadly it can't print the nice graphics because it only has 512k of memory and can't be upgraded.  I was wondering if there was any software out there for my printer that can buffer the print job in the computer's memory and slowly feed it to my printer so that my printer won't get overloaded. I'm pretty sure that's how the ink jet printer drivers work.  I just need a driver or some other solution for my printer.  Thanks in advance.

I don't think you are going to be able to print raster graphics that fill the page unless you can find a memory module for the Series II (it goes in the side of the printer). Laser printers have to have all of the data for a page in memory before they begin to image the page onto the drum. Text can be converted to bits (RIP'd) on the fly as the drum is turning. But raster data has to be completely in memory. Once the image drum begins to turn, there isn't a mechanism to stop it, accept more data, and then continue.

I can't remember how the Series II deals with lower than 300dpi resolutions. I sort of think that it expands the image to 300dpi as it's received and before imaging the drum (as oppossed to storing the image at 150dpi and expanding it on the fly) , but you could experiment with setting the graphic mode to 150dpi (esc*t150R) and see what happens.

Thanks for the reply.  I was under the impression that I couldn't upgrade them.  Do you know where I could find a memory module for it?  I see the side slot you are talking about.  I thought it was only for PostScript upgrades.

I suspect that you'd have to find a used one some where now. You could check with one of the third party memory suppliers, like Kingston (www.kingston.com). They don't show a module for a Series II, but do for a lot of other old LaserJets. It could well be that one of those modules would work.

BTW, did you check to see if any of the units you canabilized for parts had a memory module?

Oops, reposted the wrong reply.

The cannibalized LJ's were actually Apple LW2's I wouldn't be able to get a memory module from them.  Thanks for all the help
