Why when I print the PDF is the print-out not in the same size as the print-out of the pcl file? This is because Acrobat has resized the page to fit on the printable area of the paper. (Acrobat doesn't spot that there is nothing printed in the border.) The characters are not rendered very clearly when viewing the PDF at low magnification. By default, text is represented as characters using PDF bitmapped (type 3) fonts. Acrobat does not render these very well at small sizes, though the file will print correctly. Try turning off 'Smooth text and monochrome images' from the Acrobat 'File|Preferences' menu. It is possible to set up substitute outline fonts, in particular Times Roman, Helvetica and Courier are always available. These will often produce a better result for PDF viewing purposes. If you supply details of any scalable fonts to RedTitan we can set up metrics which will allow Acrobat to display a similar substitute font. This is a good way of reducing the size of the PDF by not including fonts in the document but will not work for unusual styles or scalable logos/signatures. Why are some horizontal lines thicker than others when I use Adobe to view a PDF file converted from PCL? Some PDF viewers display rounding errors at low magnification. Zoom in to the page and you will see that lines of equal thickness in the original and converted files will appear correctly in the viewer too. PCL describes lines in terms of their position and thickness. EscapeE correctly maintains these parameters. Some PDF viewers, however, convert the lines to (PostScript-style) outlines; thus a horizontal line fills the area between an upper and a lower boundary. Calculating the positions of these boundaries gives rise to rounding errors, which become particularly noticeable at low magnification. Vertical lines may display poorly for similar reasons. When files are converted to PDF is the content of the PDF file 'text' or is it 'bit mapped'? Any text in the input PCL document will be output as text in the PDF document which EscapeE creates. Some drivers, however, output certain types of text as graphics, so if your input PCL file was created by one of these, the "text" may not be quite what it seems! If you want to check that the text really is in the PDF you can (temporarily) change the PDF advanced options to output 'uncompressed' and to 'combine text strings together' and look at the PDF with a text editor. Is it possible to edit or extract text from the PDFs after they are created? Any text in the original file will be present in the exported PDF file so a PDF editor would allow text editing and searching. It might be necessary to change the code conversion table for output from certain drivers - see Font display issues. RedTitan can supply Plug-ins ("AddText" and "MoveText") for EscapeE; these enable you to edit the document before it is exported to PDF. Does EscapeE implement PDF security features? Yes, version 4.50 allows users to set passwords for access to documents and to control:
