Networked HP 1022 text errors on Windows 7 (32-bit)

Question

We have a networked HP Laserjet 1022n that works OK with older PCs, but NOT OK with Windows 7 (32-bit).
1. Text characters are always gibberish from the Win7 PC. Upgrading from MS Office 2010 to 2013 did not fix problem. Web browsers (usually Firefox, Chrome) also print garbage text; either whole page is bad or just bad header/footer text. 
2. Printer network connection often hangs up after attempting a print from the Win7 PC, but not from other PCs (WinXP; MS Office 2003, 2007).
3. Text documents print OK from MS Notepad.
4. Images normally print OK alone or in documents, but also hang up printer connection sometimes.
HP Print and Scan Doctor tool detected an "Unknown Error (06)" but could not identify or fix it. Microsoft FixIt scan tool says everything is OK, unless the network connnection is hung up (after attempting to print). Test prints are OK, both from PC software and from printer buttons.
