Memory upgrade of my HP 4250 Laserjet printer

Tuesday, February 24th, 2015

For merely $20 i ugpraded my Laserjet HP 4250 printer from 64MB to 320MB memory. It means that I can just send it a .pdf and it will print it. Cool actually. Works well in these mobilephone times where not all phones have drivers for printers.

Upgrading HP LaserJet 4250 fw

Friday, February 13th, 2015

To my joy I noticed that my HP LaserJet 4250 had an ancient FW. Not that the newer firmwares provided anything useful in my case. Neither bugfixes for bugs that I was hit by, or features that I longed for. The process of FW upgradinga HP LaserJet 4250 to a newer FW is actually quite simple. Here goes
