[GEM Development] HP Laserjet 6P

[Thomas Clayton]

Much as I thought (about the driver issue).

The difference between the 6P and the 6MP is, as you said.



In detail, the the 6P has PCL 5 built-in  to a ROM, 2MB RAM built-in, and 3 open RAM slots. The 6MP has the same PLUS one RAM slot is used (leaving two open) for a Postscript ROM module with 1MB RAM on it as well. (This gives 3MB for an 6MP.)

The RAM slots take ordinary 70nS 72-pin fast-page mode (FPM) SIMMS; < or = 16MB per slot. The "chip arrangement" seems to not matter. x8, x9 or x2 (lying on their 'side') have all functioned. BTW, I've _occasionally_ found 60nS ones to work. (I've NEVER had ANY Extended Data Out (EDO) SIMMs to function.) With, say, 12MB present; it's about 30 seconds to the "Ready" state is reached, from turn on. 

Holding the first button down (while turning on OR for ?four? seconds while already on) gives one type of print-out (I think the "demo page"). Holding BOTH, it and the "long" button down gives you the other (the "tech details" page). (I could have these backwards!)

There. MORE than you EVER wanted to know about LJ 6 P / MP printers.


Sincerely,

Thomas Clayton
