Broke/Fixed it

My boss was complaining that his printer would not print a document that a collaborator had sent him. The document in question was a large PDF with many many objects. He was considering purchasing a new printer.


The printer in question was a laserjet 6mp with 1 meg of RAM.

I suggested that we try an alternate approach first; there are many 90's era printers in the pile of equipment that gets sent to salvage. I scrounged through all the printers, and found a few laserjet 5's that used the same 72 pin SIMMs with the 'magic' hp presence detect. I mined about 6 SIMMs with capacities unknown. I put the largest looking ones (more chips==more ram?) in the printer, including one that had a postscript rom from the Laserjet 5. The test page showed that postscript was no more, but that the printer had 14 megs of RAM. Score!

A few test prints showed that it would now print the documents. I noticed, however, that the printer ram in the driver was still stuck at 1 megabyte. IT has this section blocked through GPO (we can install printers, but not modify settings).

Apparently, printing to PCL instead of postscript was the real "fix".
