After trawling through reams of forum info it appeared that the only solution was to use the 430 designjet plotter driver which worked but only in black and white / greyscale. However, I did eventually find a solution thanks to user jdm13 on the HP forums.
hp designjet 450c driver windows 7
Update 7/5/13 from user Jeff Anderson I had the driver but, thought it was buggy because I kept getting a corruption error when I tried to install it in windows 8. But, I learned that I just needed to temporarily turn off Integrity checks and it loaded fine.
I bought a laptop with windows 7 64 bit, connected to the plotter HP 450C A / 0 with usb adapter, installed the drivers I downloaded from this post, I select my model (HP 450C) and I try to print but nothing is printed.What did I do wrong, may be the parallel cable / usb wrong?thanks
Hi, yes, use any 64 bit windows driver you can find. Vista should be fine. Any driver exe file that has this name--at least this was the last file name I saw--this is for I think only for the black and white HP Designjet 430:
As you probably know many are using this driver for the 450C, 650C, 750C, etc. to work with Win 8, 8.1, and 10. But I think you have to disable windows driver signature enforcement although I think I used it once and did not have to do that.:
Per Susan with myolddesignjet.com, the following hp driver is 64-bit for these legacy printers 750C, 450C, 650C, etc.--I hope it works, although I thought it is 32-bit because of the "32" but I've been assured it is for 64-bit Windows. I think you have to defeat Win 10 driver signing, probably do have to do that, not totally sure about that.
If the driver listed is not the right version or operating system, search our driver archive for the correct version. Enter HP Designjet 450c Printer into the search box above and then submit. In the results, choose the best match for your PC and operating system.
