Here's a thing. 

When I print a PDF of say a document of text I get a strange result.

Instead of the text being at right angles to the page edge the text 'slopes' upwards about 5° from the baseline.

It only happens with PDF files — other file types such as .doc print as expected.

I've tried printing the same files from a different computer — a MacBook pro — over WIFI I get the same result.

The printer is a postscript laser printer connected to a USB port of a Mac desktop computer working as a print server.

Grateful for the help and guidance of forum members.

Many thanks

Hello Ulsinus,

This is a strange issue indeed.

You mentioned that the problem only happens with PDFs. This could be a clue to identify where the problem is. When a PDF is printed on a PostScript printer, usually Acrobat will convert the PDF to PostScript and send the PostScript directly to the printer.

Other software, like MS word, would use the print functionality in the operating system, and the OS would generate the PostScript for the printer.

So the rotation seems to be caused by some extra PostScript that is being added to the file generated by the application used to print the PDF.

It's difficult to pinpoint exactly where this could be happening. The best course of action would be to use a process of elimination.

If possible, are you able to try the same printer but on a different Mac? If the problem still happens then that would isolate the problem to the printer itself.

Alternatively, is it possible to try the same Mac but using a different PostScript printer of the same make/model? If the problem still happens in this scenario the issue can be isolated to the Mac.

One quick fix might be to remove the printer from the print settings on the Mac, and then add the printer again. This would reset the printer preferences and could fix the issue.

Another idea would be to try and get the PostScript file before it is sent to the printer. Maybe there is a print to file option, or some tool that could retrieve the printer spool file? If a PostScript viewer was used on the file and the text is rotated there, that would further isolate the issue. We could help you analyse the PostScript to see what command has been added to rotate the text in the way you described.
