If a Postscript job is big because of of its fonts, font memory of a chosen output device may not be enough to load the font resources. There are ways to resolve this issue.
PostScript or PDF fonts are normally Type 1 fonts and will automatically sent to device as outline fonts. If this method bloats the memory of the device; send only the fonts that are used by the job as bitmap format instead. This is by having PSIN_CREATE_OUTLINE_VDFS=NO.
Sometimes IPDS Printers would not print text of 36 point high fonts. With the current PI Output Manager releases, these text will be sent, with its font; for example Arial font family in 36 point high, even only COPY is what is required to print. COPY could be converted to an image by having PSIN_FONT_SIZE_MAX=35. This will convert all fonts of 35 points high and above, to images.
Another that can require lots of memory to handle are the oblique texts. With PSIN_OBLIQUE_TEXT_AS_IMAGES=YES, these oblique texts can be in image instead.
Just remember when text are rastered, the word with these texts are lost. Also rastered text to image might lose it color.
