Type and Size
Printing by Type or Size means you want the printer to pull paper from the first tray that is loaded with the type or size that you choose. Selecting paper by type rather than source is similar to locking out trays and helps protect special paper from accidental use. (However, selecting the Any setting does not enable this tray lock-out function.) For example, if a tray is configured for letterhead, and you specify the driver to print on plain paper, the printer will not pull the letterhead from that tray. Instead, it will pull paper from a tray that has plain paper loaded and is configured for plain paper on the printer control panel. Selecting paper by type and size results in significantly better print quality for heavy paper, glossy paper, and transparencies. Using the wrong setting can result in unsatisfactory print quality. Always print by Type for special print media, such as labels or grayscale transparencies. Always print by Size for envelopes.
If you want to print by Type or Size and the trays have not been configured for a certain type or size, load the paper or print media into Tray 1. Then, in the printer driver, select the Type or Size from the Page Setup dialog box, the Print dialog box, or the Print Properties dialog box.
If you often print on a certain type or size of paper, the printer administrator (for a network printer) or you (for a local printer) can configure a tray for that type or size. See Using the embedded Web server (HP Color LaserJet 3700 series printer only) or Configuring trays for type and size. Then, when you choose that type or size as you print a job, the printer pulls from the tray configured for that type or size.
Every time Tray 2 or the optional Tray 3 is closed, a message appears prompting you to choose a Type or Size for the tray. If the tray is already configured correctly, press to return to the Ready state.
