Printing incomplete or partial pages using HP Deskjet 845C

I'm not familiar with the 845C, but I have a 895Cse. I went from Tiger to 10.5.4 last week and the printer did something like you mentioned: it would print one line of "garbage", then sucked-in another sheet of paper to print correctly. When the print job finished, the printer would be frozen and required to be turned off / on for the next print job.

I contacted HP and they said some older printers were having trouble with Leopard. They gave easy to understand instructions to, I believe, revert to older "drivers". I followed their instructions this morning and things seem to be operating correctly. I could forward their email to you if you are interested in looking it over.

There may be other HP users that may find the answer from interesting:



Thank you for contacting HP Total Care.

There were some issues with the drivers preloaded on Leopard for a few of the older printers. Please follow the steps below to manually uninstall/reinstall with a different driver.

1. Remove the HP Print Drivers installed.

NOTE: If you have any other HP printers they may have to be reinstalled.

a. Open the hard drive volume (by default labeled Macintosh HD).
b. Select Library.
c. Select Printers.
d. Single-click on the HP folder and drag it to the Trash.

2. Clearing Preferences:

a. Open the hard drive volume
b. Select Library.
c. Select Preferences.

i. Select Library.
j. Select Preferences.
k. Delete any file starting with Com.Apple.Print.
l. Select By Host.

3. Once the HP folder has been removed it is important to repair the disk permissions. Please complete the following steps:

a. Open the hard drive volume (by default labeled Macintosh HD).
b. Double-click Applications.
c. Double-click Utilities.
d. Double-click Disk Utility.
e. Single-click on the name of your hard drive located on the left (usually says Macintosh HD).

Once the drivers are installed, ensure the printer is plugged in through USB and follow the steps below to add the printer.

The HP email didn't specify if PPC or Intel. I would think its software and not hardware related.

By the way, later this afternoon "Software Update" had an update for HP printers. Talk about timing! I didn't download it because I was afraid it would screw up what I already did!
